  • Product introduction

The A3909 is a dual-socketFull-bridge motor drives, designed for 12 V medium power applications. The output is rated at a supply voltage range of 4 to 18 V with currents up to 1 A per phase.

Outputs can be paralleled in higher current single DC motor applications.

Four inputs (IN1 to IN4) control forward, reverse, braking and coasting modes for DC motors, or full-step and half-step modes for bipolar stepper motors.

The A3909 is available in a 10-pin MSOP package with exposed heat sink (suffix LY) and a 10-pin SSOP package (suffix LN) for wave soldering applications. Both packages are lead (Pb) free and the leadframes are 100% matte tin plating.

  • Low RDS (On)output
  • Two DC motors or a single stepper motor can be driven
  • Low-power standby (sleep) mode with zero power consumption
  • Thermal shutdown protection
  • 1.8 A. Parallel operation selection of a single DC motor
  • Overcurrent protection:
    • The output is shorted to the power supply
    • The output is shorted to ground
    • The output load is shorted
