ELECTRIC TOY DC MOTOR
DRIVE CIRCUIT
DESCRIPTION
UTC UMD9112 is an integrated circuit driven by a single
channel toy DC motor which is designed for low-voltage operated
system. 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.
SOP-8
UTC UMD9112 has on-chip temperature protection function.
When load motor with low internal resistance is in locked rotor,
UTC UMD9112 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 150°C) set by internal
temperature protection circuit, the internal circuit will switch off the
on-chip power switching transistor of UTC UMD9112, and switch
off load current, preventing potential safety hazards such as
fuming, igniting, etc. Of plastic package caused by over
temperature .Only after having confirmed that the circuit has
returned to safety temperature, can the on-chip temperature
hysteresis circuit be allowed to re-control the circuit.
FEATURES
* H bridge driver of internal PMOS/NMOS power switches
* Can realize 4 functions (forward、backward、standby、brake) of
load motor
* Low output impedance
* Low standby current (typ.0.1μA)
* Low static operational current (typ.300μA, VCC=3V)
* On-chip thermal shut down (TSD) with hysteresis

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Maximum power dissipation at different ambient can be obtained from the following formula
PD=(TJ-TA)/θJA.
Where TJ is junction temperature with the circuit working, and TA is the ambient temperature with the
circuit working.
3. Method of calculation of circuit power dissipation
P=I2×R
Where P is circuit power dissipation, I is continuous output current, and R is circuit output on-resistance.
Circuit power dissipation P must be smaller than maximum power dissipation PD.

APPLICATION INFORMATION
1. Baseline Mode
a) Standby mode
In standby mode, INA=INB=L. All internal circuits, including the drive power tube, are off state. Circuit
consumption is extremely low. In this mode, OA and OB both are in high-impedance state.
b) Forward mode
The forward mode is defined as: INA=H, INB=L, at this point the motor drive end OA outputs high level, and the
motor drive end OB outputs low level, then the motor drives the current into the motor from the OA, and out from the
OB to the ground. This motor rotation mode is defined as the forward mode.
c) Backward mode
The backward mode is defined as: INA=L, INB=H, at this point the motor drive end OB outputs high level, and
the motor drive end OA outputs low level, then the motor drives the current into the motor from the OB, and out from
the OA to the ground. This motor rotation mode is defined as the backward mode.
d) Brake mode
The brake mode is defined as: INA=H, INB=H, at this point motor drive ends OA and OB both output low level,
and the energy stored in the motor will be quickly released through the OA end’s NMOS tube or the OB end’s NMOS
tube, so the motor will stop turning in a short time.
Note: in brake mode, circuit will consume static power.
