Single-chip motor driver targets IoT
A single-chip 2.6 A driver for brushed DC motors, STMicroelectronics’ STSPIN250 targets battery-powered portable and wearable applications. This low-voltage, energy-efficient driver integrates a power MOSFET bridge and fixed off-time PWM current controller in a tiny 3×3 mm VFQFPN package.
The STSPIN250 offers a low on-resistance power stage, just200 mΩ¦ total for both high side and low side, and standby current consumption of less than 80 nA to help maximize battery runtime and minimize equipment case temperature. In addition, a supply voltage range of 1.8 V to 10 V allows designers to specify a power source as small as a single Li-ion cell.
