Brushed DC Motor Driver serves battery-powered applications.
Press Release Summary:
Supplied in 2 x 2 mm WSON package, DRV8837 is 1.8 A brushed DC motor driver with R(DS(ON)) of 280 mohms and sleep current as low as 35 nA that improve thermal performance and extend battery life in diverse applications. Separate logic and motor supplies improve performance in battery-powered applications during start up and stall conditions. Along with 1.8-11 V operating range, driver features over-current, over-temperature, shoot-through, and under-voltage protections.
Original Press Release:
TI Introduces Industry's Smallest 1.8-A brushed DC Motor Driver for Battery Powered Applications
DALLAS -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today expanded its growing family of low-voltage DRV8x motor drivers with the industry's smallest 1.8-A brushed DC motor driver. The DRV8837 is 75 percent smaller than the nearest competitor, enabling smaller, sleeker, more innovative system design. It also extends battery life and improves thermal performance in battery-powered or low-voltage motion control applications by reducing R(DS(ON)) by 50 percent and sleep current by 75 percent, compared to existing devices. For more information or to place an order, visit www.ti.com/drv8837-pr.
Key features and benefits of the DRV8837:
-- Extends battery life: Low R(DS(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.
-- Improves performance: Separate logic and motor supplies improve performance in battery powered applications during start up and stall conditions.
-- Wide/low-voltage operating range: 1.8-V to 11-V operating range supports up to 6-stack alkaline or 2-stack Li-ion battery pack applications.
-- Reduces board space: Tiny 2-mm x 2-mm WSON package enables smaller, sleeker design.
-- Advanced on-chip protection: Over-current, over-temperature, shoot-through and under-voltage protection increase system reliability and reduce design complexity.
Tools and support
The DRV8837 evaluation module is available today for a suggested retail price of US$25. Features of the DRV8837EVM include:
-- On-board speed, sleep and direction controls.
-- Micro-USB connection for easy evaluation/power-up.
-- On-board MSP430 microcontroller (MCU) to fully evaluate DRV8837 performance with the added flexibility to use an external MCU.
-- Easy access to critical control and test points.
Package, availability and pricing
The DRV8837 is available now in an 8-pin, 2-mm x 2-mm WSON package for US$0.45 in 1,000-unit quantities.
Drop in and spin with DRV8x motor drivers
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.
