DRV8837

Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This TI datasheet covers the DRV8837 and DRV8838 low-voltage H-bridge motor drivers. Designed for battery-powered applications like cameras, toys, and robotics, these devices drive DC motors or solenoids using integrated N-channel MOSFETs in an H-bridge configuration. Key parameters include 1.8A maximum drive current, 280mΩ total on-resistance, and a motor supply range of 0 to 11V with logic supplies from 1.8 to 7V. Both parts feature PWM or pulse-mode interfaces along with robust protection against overcurrent, thermal shutdown, and undervoltage lockout. The DRV8837 uses PWM inputs while the DRV8838 supports phase-enable control.
