Low voltage dual brush DC motor driver

STSPIN240
Low voltage dual brush DC motor driver
The STSPIN240 is a dual brush DC motor driver integrating a low RDS(ON) power stage in a small QFN 3 x 3 mm package. Both the full-bridges implement an independent PWM current controller with fixed OFF time. The device is designed to operate in battery-powered scenarios and can be forced into a zero- consumption state allowing a significant increase in battery life. The device offers a complete set of protection features including overcurrent, overtemperature and short-circuit protection.

Key Features
  • Operating voltage from 1.8 to 10 V
  • Maximum output current 1.3 Arms
  • RDS(ON) HS + LS = 0.4 Ω typ.
  • Current control with programmable off-time
  • Full protection set
    • Non-dissipative overcurrent protection
    • Short-circuit protection
    • Thermal shutdown
  • Energy-saving and long battery life with standby consumption less than 80 nA
