Description
Combining low-power CMOS-compatible logic with highcurrent, high-voltage power MOSFET outputs, the STA6940M provides complete control and drive for brush DC motors.
Features
- Power supply voltage, VBB , 44 V maximum, 10 to 40 V normal operating range.
- Logic supply voltage, VDD , 3 to 5.5 V compatible.
- Output current, IO ,4 A average, 8 A maximum.
- Output elements are all N-channel MOSFETs to reduce
losses.
- Internal charge pump.
- Forward, reverse, free, and brake control modes available.
- Constant-current control:
▫ Off-time 35 μs, fixed (Slow Decay mode).
- Internal Overcurrent Protection (OCP) circuitry
▫ Off-time 142 μs fixed (Fa.
