Texas Instruments DRV8262 H-Bridge Motor Driver

Texas Instruments DRV8262 H-Bridge Motor Driver is a wide-voltage, high-power, H-bridge motor driver for various industrial applications. The device integrates two H-bridges to drive two DC motors or a bipolar stepper motor. The H-bridges can be paralleled to drive one DC motor with a higher current. The DRV8262 supports up to 16A peak current in the dual H-bridge mode and 32A in the single H-bridge mode. The device also integrates current sensing and regulation, current sense output, and protection circuitry.

Integrated current sensing across the high-side MOSFETs allows the driver to regulate the motor current during startup and high-load events. A current limit can be set with an adjustable external voltage reference. Additionally, the device provides an output current proportional to the motor current for each H-bridge. The integrated sensing uses a current mirror, removing the need for large shunt resistors, saving board area, and reducing system cost.

A low-power sleep mode is provided to achieve ultra-low quiescent current. Internal protection features for the Texas Instruments DRV8262 are provided for supply undervoltage lockout (UVLO), charge pump undervoltage (CPUV), output over current (OCP), and device overtemperature (OTSD).
