Bridge Driver (incl. Charge Pump)
26.1
Features
The MOSFET Driver is intended to drive external normal level NFET transistors in bridge configuration. The driver
provides many diagnostic possibilities to detect faults.
Functional Features
• External Power NFET Transistor Driver Stage with driver capability for max. 100 nC gate charge @ 25 kHz
switching frequency.
• Implemented adjustable cross conduction protection.
• Supply voltage (VSD) monitoring incl. adjustable over- and undervoltage shutdown with configurable interrupt
signalling.
• VSD operating range down to 5.4 V
• VDS comparators for short circuit detection in on- and off-state
• Open-Load detection in off-state
26.2
Introduction
The MOSFET Driver Stage can be used for controlling external Power NFET Transistors (normal level). The
module output is controlled by SFR or System PWM Machine (CCU6).
