DESCRIPTION

UTC UMD9114 is an integrated brush DC motor drive solution
1
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.
SOT-26
UTC UMD9114 has on-chip temperature protection function.
When load motor with low internal resistance is in locked rotor,
UTC UMD9114 output current will increase momentarily, power
dissipation of the circuit will go up sharply, and the chip
temperature will soar. But, when the chip temperature exceeds a
maximum temperature point (typically 160°C) set by internal
temperature protection circuit, the internal circuit will switch off the
on-chip power switching transistor of UTC UMD9114, and switch
off load current, preventing potential safety hazards such as
fuming, igniting of plastic package caused by over temperature etc.
Only after having confirmed that the circuit has returned to safety
temperature, the on-chip temperature hysteresis circuit can be
allowed to re-control the circuit.
FEATURES

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
2.0uA input current when input voltage is 3V
* On-chip thermal shut down (TSD) with hysteresis
* ESD rate: 2.5KV(HBM)
