Description
The A3921 is a full-bridge controller for use with external N‑channel power MOSFETs and is specifically designed for automotive applications with high-power inductive loads, such as brush DC motors.
Features
- High current gate drive for N-channel MOSFET full bridge.
- 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.
- 5.5 to 50 V supply voltage range.
- Integrated 5 V regulator.
- Diagnostics output.
- Low current sleep mode.
- AEC-Q100 qualified
Package: 28-pin TSSOP with exposed thermal pad (suffix L.
