STA6940M - Brushed DC Motor Driver

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.

It provides internal fixed off time, pulse-width modulation (PWM) control of the output current, rated for 4 A normal operating level.

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.
