The Texas Instruments DRV8837CDSGR is a single-channel brushed DC motor driver rated for 1A of output current, supplied in an 8-pin WSON with exposed pad measuring 2mm by 2mm with an 800um height. A driver of this class integrates the H-bridge power stage, so a microcontroller PWM output can set motor speed and direction directly without external FETs or a gate driver. It carries a 150C maximum junction temperature, is specified from -40C to 85C ambient, and the record lists a 250 k Hz switching frequency. Note the supply attributes read 0V minimum and 11V maximum against a 1.8V to 7V range in the product title, and the output count is recorded as 1 for a device that drives a full bridge; the supply range should be confirmed against the manufacturer datasheet.

Low-voltage single-channel motor drivers such as the DRV8837CDSGR drive the small brushed DC motors and actuators inside battery-powered products: camera lens, zoom and shutter mechanisms, valve and latch actuators, paper feed and carriage motors in printers and scanners, brush and side motors in robot vacuums, small pumps, toys and vibration motors. The same H-bridge is also used to drive solenoids, latching relays and a single stepper winding where bidirectional current is needed. A supply range that starts below 2V is what allows direct operation from one or two cells without an intermediate boost stage. The 2mm by 2mm package lets a design place one driver per motor in a handheld product rather than routing everything back to a central driver.
