PG-DSO-28-22
Description The BTM7700G is part of the TrilithIC family containing three dies in one package: One double high-side switch and two low-side switches. The drains of these three vertical DMOS chips are mounted on separated lead frames. The sources are connected to individual pins, so the BTM7700G can be used in H-bridge- as well as in any other configuration. The double high-side switch is manufactured in SMART SIPMOS(R) technology which combines low RDS ON vertical DMOS power stages with CMOS circuitry for control, protection and diagnosis. To achieve low RDS ON and fast switching performance, the low-side switches are manufactured in S-FET logic level technology.

Circuit Description
Input Circuit
The control inputs IH1,2 consist of TTL/CMOS compatible Schmitt-Triggers with hysteresis. Buffer amplifiers are driven by these stages and convert the logic signal into the necessary form for driving the power output stages. The inputs are protected by ESD clamp-diodes. The inputs IL1 and IL2 are connected to the gates of the standard N-channel vertical power-MOS-FETs.
4.2
Output Stages
The output stages consist of an low RDSON Power-MOS H-bridge. In H-bridge configuration, the D-MOS body diodes can be used for freewheeling when communicating inductive loads. If the high-side switches are used as single switches, positive and negative voltage spikes which occur when driving inductive loads are limited by integrated power clamp diodes.
4.3
Short Circuit Protection
The outputs are protected against short circuit to ground and short circuit over load An internal OP-Amp controls the Drain-Source-Voltage by comparing the DS-Voltage-Drop with an internal reference voltage. Above this trip point the OP-Amp reduces the output current depending on the junction temperature and the drop voltage.
4.4
Overtemperature Protection
The high-side switches also incorporate an over temperature protection circuit with hysteresis which switches off the output transistors and sets the status output to low.
4.5
Undervoltage Lockout
When VS reaches the switch-on voltage VUVON the IC becomes active with a hysteresis. The high-side output transistors are switched off if the supply voltage VS drops below the switch off value VUVOFF.
4.6
Status Flag
The status flag output is an open drain output with zener-diode which requires a pull-up resistor, as shown in the application circuit in Figure 4 "Application Example BTM7700G" on Page 15. Various errors as listed in the table "Diagnosis" are reported by switching the open drain output ST to low.
