1.0 GENERAL DESCRIPTION
The DDX-2102 power device is a monolithic, dual channel H-Bridge that can provide audio power up to 65 watts per channel @10%THD, 8 at very high efficiency. The device contains a logic interface, integrated bridge drivers, high efficiency MOSFET output transistors and protection circuitry. It may be used in DDX(R) Mode as a dual bridge or reconfigured as a single bridge with double the output current capability. Alternatively, in Binary Mode, it may be configured as either a dual bridge or (at lower power output) a quad half-bridge or a combination of both types. The benefits of the DDX(R) amplification system are: an all-digital design that eliminates the need for a digital to analog converter (DAC), and the high efficiency operation derived from the use of Apogee's patented damped ternary pulse width modulation (PWM). This approach provides an efficiency advantage over conventional PWM designs and more than three times the efficiency of Class A/B amplifiers with music input signal.

3.0 DDX-2102 POWER DEVICE
The DDX-2102 Power Device is a dual channel H-Bridge that can deliver more than 65 watts per channel (<10%THD) of audio output power at very high efficiency. It converts both DDX(R) and binarycontrolled PWM signals into audio power at the load. It includes a logic interface, integrated bridge drivers, high efficiency MOSFET outputs, and thermal and short circuit protection circuitry. In DDX(R) mode, two logic level signals per channel are used to control high-speed MOSFET switches to connect the speaker load to the input supply or to ground in a bridge configuration, according to Apogee's patented damped ternary PWM. In Binary Mode operation, both Full Bridge and Half Bridge Modes are supported. This device includes over-current and thermal protection as well as under-voltage lockout with automatic recovery. A thermal warning status is also provided.

3.1
Logic Interface and Decode
The DDX-2102 power outputs are controlled using one or two logic level timing signals. In order to provide a proper logic interface, the VL input must operate at the same voltage as the DDX(R) controller logic supply. VL (Logic Reference Voltage) is recommended to be powered and stable prior to Vcc achieving > 7V to assure proper power up sequence. VL is recommended to remain powered and stable until after Vcc has decayed below 7V during power removal. 3.2 Protection Circuitry
The DDX-2102 includes protection circuitry for over-current and thermal overload conditions. A thermal warning pin TWARN is activated low (open-drain MOSFET) when the IC temperature exceeds 130C, in advance of the thermal shutdown protection. When a fault condition is detected (logical OR of overcurrent and thermal), an internal fault signal acts to immediately disable the output power MOSFETs, placing both H-bridges in a high impedance state. At the same time an open-drain MOSFET connected to the FAULT pin is switched on. There are two possible modes subsequent to activating a fault. The first is a SHUTDOWN mode. With FAULT (pull-up resistor) and TRI-STATE pins independent, an activated fault will disable the device, signaling low at the FAULT output. The device may subsequently be reset to normal operation by toggling the TRI-STATE pin from High to Low to High using an external logic signal. The second is an AUTOMATIC recovery mode. This is depicted in the application circuit in Figure 19. The FAULT and TRI-STATE pins are shorted together and connected to a time constant circuit comprising of RT and CT. An activated FAULT will force a reset on the TRI-STATE pin causing normal operation to resume following a delay determined by the time constant of the circuit. If the fault condition is still present, the circuit operation will continue repeating until the fault condition is removed.

DDX-2102
An increase in the time constant of the circuit will produce a longer recovery interval. Care must be taken in the overall system design so as not to exceed the protection thresholds under normal operation. 3.3 Power Outputs
The DDX-2102 power and output pins are duplicated to provide a low impedance path for the device's bridged outputs. All duplicate power, ground and output pins must be connected for proper operation. The PWRDN or TRI-STATE pins should be used to set all MOSFETS to the Hi-Z state during power-up until the logic power supply, VL, is settled. 3.4 Parallel Output/High Current Operation
When using DDX(R) Mode output, the DDX-2102 outputs can be connected in parallel to increase the output current to a load. In this configuration the device can provide over 130W@4 (see Figure 7). This mode is enabled with the CONFIG pin connected to VREG1 and the inputs combined INLA = INLB, INRA = INRB and outputs combined OUTLA = OUTLB, OUTRA = OUTRB. 3.5 3.6 ADDITIONAL INFORMATION Output Filter
A passive two-pole low-pass filter is used on the DDX-2102 power outputs to reconstruct an analog signal. System performance can be significantly affected by the output filter design and choice of components. (See appnote: AN-15, Component Selection for DDX Amplifiers.) A filter design for 6/8 loads is shown in the Typical Application Circuit in Figure 19. Figure 20 shows a filter design for 4 loads. Figure 22 shows a filter for 1/2 bridge mode, 4 loads. 3.7 Power Dissipation & Heat Sink Requirements The power dissipated within the device will depend primarily on the supply voltage, load impedance, and output modulation level. The surface mount package of the DDX-2102 includes an exposed thermal slug on the top of the device to provide a direct thermal path from the integrated circuit to the heatsink. Careful consideration must be given to the overall thermal design. See Figure 5 for power derating.

Figure 6 shows the full-scale output power (0dB FS digital input with unity amplifier gain) as a function of Power Supply Voltage for 4, 6, and 8 Ohm loads in either DDX(R) Mode or Binary Full Bridge Mode. Output power is constrained for higher impedance loads by the maximum voltage limit of the DDX-2102 IC and by the over-current protection limit for lower impedance loads. The minimum threshold for the over-current protection circuit is 3.5A (at 25 C) but the typical threshold is 6A. Solid curves depict typical output power capability of each device. Dotted curves depict the output power capability constrained to the minimum current specification of the DDX-2102. The output power curves assume proper thermal management of the power device's internal dissipation. See Figure 5. NOTE: Output power at 10% THD is approximately 30% higher.
