MOS INTEGRATED CIRCUIT
PD16857
MONOLITHIC 6 channel H-BRIDGE DRIVER
DESCRIPTION
PD16857 is monolithic 6 channel H-bridge driver employing power MOS FETs in the output stages. The MOS
FETs in the output stage lower the saturation voltage and power consumption as compared with conventional drivers using bipolar transistors. In addition, a low-voltage malfunction prevention circuit is also provided that prevents the IC from malfunctioning when the supply voltage drops. A 30-pin plastic shrink SOP package is adopted to help create compact and slim application sets. In the output stage H bridge circuits, two low-ON resistance H-bridge circuits for driving actuators, and another three channels for driving sled motors and tilt control, and another channel for driving loading motor are provided, making the product ideal for applications in DVD-ROM/DVD-RAM.
FEATURES
* Six H-bridge outputs employing power MOS FETs. * High speed PWM drive corresponding: Operating input frequency 120 kHz (MAX.) * Low voltage malfunction prevention circuit: Operating control block voltage under 2.5 V (TYP.) * Loading into 38-pin shrink SOP (300 mil).

ABOUT SWITCHING OPERATION
VM
When output A is switched as shown in the figure on the right, a dead time (time during which both Pch and Nch are off) elapses to prevent through current. Therefore, the waveform of output A (rise time, fall time, and delay time) changes depending on whether output B is fixed to the high or low level. The output voltage waveforms of A in response to an input waveform where output B is fixed to the low level (1) or high level (2) are shown below.
Nch Nch A B Pch Pch
(1) Output B: Fixed to low level Output A: Switching operation (Operations of Pch switch and Nch switch are shown.)
Dead time Input waveform
Pch : OFF OFF ON Nch : ON OFF OFF
ON OFF
OFF OFF OFF ON
Voltage waveform at point A Current ON
Current OFF
Output A goes into high-impedance state and is in an undefined status during the dead time period. But, because output B is pulled down by the load, a low level is output to A. (2) Output B: Fixed to high level Output A: Switching operation (Operations of Pch switch and Nch switch are shown.)
Dead time Input waveform
Pch : OFF OFF ON Nch : ON OFF OFF
ON OFF
OFF OFF OFF ON
Voltage waveform at point A Current OFF
Current ON
Output A goes into high-impedance state and is in an undefined status during the dead time period. But, because output B is pulled up by the load, a high level is output to A.

Data Sheet S13908EJ1V0DS00
PD16857
The switching characteristics shown on the preceding pages are specified as follow ("output at one side" means output B for H-bridge output A, or output A for output B). [Rise time] Rise time when the output at one side is fixed to the low level (specified on current ON). [Fall time] Fall time when the output at one side is fixed to the high level (specified on current ON). [Rising delay time] Rising delay time when the output at one side is fixed to the low level (specified on current ON). [Falling delay time] Falling delay time when the output at one side is fixed to the high level (specified on current ON). [Change in rising delay time] Change (difference) in the rising delay time between when the output at one side is fixed to the low level and when the output at the other side is fixed to the high level. [Change in falling delay time] Change (difference) in the falling delay time between when the output at one side is fixed to the low level and when the output at the other side is fixed to the high level. [Rising delay time differential] Difference in rising delay time between output A and output B. [Falling delay time differential] Difference in falling delay time between output A and output B. Caution Because this LSI switches a high current at high speeds, surge may occur due to the VM and GND wiring and inductance and degrade the performance of the LSI. On the PWB, keep the pattern width of the VM and GND lines as wide and short as possible, and insert the bypass capacitors between VM and GND at location as close to the LSI as possible. Connect a low inductance magnetic capacitor (4700 pF or more) and an electrolytic capacitor of 10 F or so, depending on the load current, in parallel.

The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance.
