Key Features
- Operation from 5 V to 60 V Supply Voltage with Tolerance from 4 V to 70 V
- Constant Current Drive of Power FET, Configurable from 5 mA to 250 mA (16 Settings by Input Level to VDRV Pin)
- Internally Generated Gate Drive Supply Voltages
- Tolerant to -12 V DC for High Side Gate and Source Output Pins
- Gate Sensing for Cross Conduction Protection and Optimized Dead Time
- Embedded High GBW General Purpose Amplifier (Intended for Current Sensing and Externally Configurable)
- Embedded Charge Pump Function Allowing DC Static Drive
- Strong Hold-off Current Preventing Self-turn-on
- Internal Gate Pull-down to GND during Loss of VDD (Core) Power
- Under Voltage Lock Out on VM, VGL, and VGH-VM with Optional Trip Levels
Applications
- Industrial Actuators and Cobots
