DRV8212 - 11-V H-Bridge Motor Driver

Description

The DRV8212 is an integrated motor driver with four N-channel power FETs, charge pump regulator, and protection circuitry.

The tripler charge pump architecture allows the device to operate down to 1.65 V to accommodate 1.8-V supply rails and low-battery conditions.

Features

  • N-channel H-bridge motor driver.
  • MOSFET on-resistance: HS + LS 280 mΩ.
  • Drives one bidirectional brushed DC motor.
  • Two unidirectional brushed DC motors.
  • One single- or dual-coil latching relay.
  • Push-pull and bistable solenoids.
  • Other resistive, inductive, or LED loads.
  • 1.65-V to 11-V operating supply voltage range.
  • High output current capability:.
  • Full-bridge: 4-A peak.
  • Half-bridge: 4-A peak per ou.
