BRUSH DC MOTOR DRIVE
CIRCUIT
DESCRIPTION
UTC UMD9115 is an integrated brush DC motor drive solution
for battery-powered toys 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, and an
output power section is able to supply an output current of up to
200mA (typical) according to the logic control.
SOP-8
The IC allows control of reversible motors in cassette players
and other electrical equipment by using CMOS-level logic signals.
UTC UMD9115 has on-chip temperature protection function.
When load motor with low internal resistance is in locked rotor,
UTC UMD9115 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 set by internal temperature protection
circuit, the internal circuit will switch off the on-chip power switching
transistor of UTC UMD9115, 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
* Built-in motor driving power transistors (typ.200mA)
* Built-in anti-common state conduction circuit.
* Direct control with the CMOS logic
* Low standby current (typ.0.1uA)
* Low static operational current
* 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, OUTA and OUTB 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 OUTA outputs high level, and
the motor drive end OUTB outputs low level, then the motor drives the current into the motor from the OUTA, and out
from the OUTB 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 OUTB outputs high level,
and the motor drive end OUTA outputs low level, then the motor drives the current into the motor from the OUTB,
and out from the OUTA 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 OUTA and OUTB both output low
level, and the energy stored in the motor will be quickly released through the OUTA end’s NMOS tube or the OUTB
end’s NMOS tube, so the motor will stop turning in a short time.
Note: in brake mode, circuit will consume static power.
