UMD9114 - DC TAIL ROTOR MOTOR DRIVER

General Description

UTC UMD9114 is an integrated brush DC motor drive solution for battery-powered toys, low-voltage or battery-powered motion control applications.

It has H bridge driver and uses the PMOS and NMOS power transistors with low output resistance.

Key Features

  • Low standby current (0.1μA typ. ).
  • PMOS and NMOS power transistors with low output resistance If IO is 100mA, RON of power transistor is 1.5Ω If IO is 200mA, RON of power transistor is 1.6Ω If IO is 300mA, RON of power transistor is 1.7Ω.
  • Built-in Subsequent stream diode.
  • No external diode required.
  • Low input current Pull-down resistance is 1.8MΩ typical 1.6uA input current when input voltage is 3V.
  • On-chip thermal shut down (TSD) with hysteresis www. unisonic. c.

UNISONIC TECHNOLOGIES CO., LTD UMD9114 Preliminary DC TAIL ROTOR MOTOR, STEERING GEAR MOTOR DRIVE CIRCUIT  DESCRIPTION UTC UMD9114 is an integrated brush DC motor drive solution for battery-powered toys, low-voltage or battery-powered motion control applications. It has H bridge driver and uses the PMOS and NMOS power transistors with low output resistance. Low on-resistance ensures the circuit to consume lower power in operating at a continuous current, and ensures the circuit to operate stably for a long time. The circuit has a wide working voltage range from 2.5V to 5V. The maximum continuous output current reaches 0.5A, and the maximum peak output current can be 0.8A when VDD is 4V. UTC UMD9114 has on-chip temperature protection function.
