The DRV8837 is 75 percent smaller than the nearest competitor, enabling smaller, sleeker, more innovative system design. The device also extends battery life and improves thermal performance in battery-powered or low-voltage motion control applications by reducing RDS(ON) by 50 percent and sleep current by 75 percent, compared to existing devices.

The DRV8837 extends battery life with a low RDS(ON) of 280 milliohms and an ultra-low sleep current as low as 35 nA improve thermal performance and extend battery life in applications such as toys, gas or water smart meters, electronic locks, micro printers and cameras.  

The device offers improved performance by using separate logic and motor supplies improve performance in battery powered applications during start up and stall conditions.

The DRV8837 has a wide/low-voltage operating range of 1.8-V to 11-V which supports up to 6-stack alkaline or 2-stack Li-ion battery pack applications.

The DRV8837 evaluation module is available for a price of $25.

DRV8x motor drivers integrate many of the functional blocks needed in a motor system, such as gate drive circuitry, MOSFETs, protection circuitry and current regulation circuitry. DRV8x motor drivers make it easy to drive a wide range of stepper, brushed DC and brushless DC motors in portable and wired applications, such as printers, video surveillance, fans, pumps, valves, power tools, textile manufacturing machines, e-locks and consumer electronics.
