Product Overview
The A3941KLPTR-T is a full bridge MOSFET driver in 28 pin TSSOP package. This is a full bridge controller for use with external N channel power MOSFETs. A unique charge pump regulator provides full gate drive (greater than 10V) for battery voltages down to 7V and allows the A3941 to operate with reduced gate drive down to 5.5V. A bootstrap capacitor is used to provide above battery supply voltage required for N channel MOSFETs. An internal charge pump for high side drive allows DC (100% duty cycle) operation. Integrated diagnostics provide indication of undervoltage, overtemperature, power bridge faults and can be configured to protect power MOSFETs under most short circuit conditions.
- High side or low side PWM switching
- Charge pump for low supply voltage operation
- Top off charge pump for 100% PWM
- Cross conduction protection with adjustable dead time
- Supply voltage range from 5.5V to 50V
- 90ns turn off propagation delay
- 90ns turn on propagation delay
- Diagnostics output
- Low current sleep mode
- Operating temperature range from -40°C to 150°C
