Low-Voltage H-Bridge Driver

SGM42537.pdf

The SGM42537 is a low voltage integrated motor driver that can be used in battery or non-battery powered applications. The N-MOSFET H-bridge output can drive brushed DC motors for motion control or other loads such as solenoids and relays. A separate supply pin (VM) is provided for the power stage that can deliver up to 3A peak current to the load from a second source. The VM voltage range is 0V to 12V while the device itself can be supplied from a low-current (< 2mA) 2V to 5.5V source (V_CC). An internal charge pump provides the gate driving voltage for the high-side switches.

The standard input interface for the SGM42537 is PWM (IN1/IN2). The device uses a dedicated nSLEEP input for sleep mode.

The SGM42537 is available in a Green TDFN-2×2-8AL package.
