UNISONIC TECHNOLOGIES CO., LTD UMD9111 Preliminary CMOS IC BRUSH DC MOTOR DRIVE CIRCUIT „ DESCRIPTION UTC UMD9111 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 curren t, and ensures the circuit to operate stably for a long time. The circuit has a wide working voltage range, the maximum contin uous output current reaches 0.8A, and the maximum peak output current reaches 1.5A. UTC UMD9111 has on-chip temperature protection function. When load motor with low internal resistance is in locked rotor, UTC UMD9111 output current will incr ease 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 ) set by internal ℃ temperature protection circuit, the in ternal circuit will switch off the on-chip power switching transistor of UTC UMD9111 , and switch off load current, preventing potential safety hazards such as fuming, igniting, etc. Of plastic package caused by over temperature .Only after having c onfirmed 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 anti-common state conduction circuit. * Low output impedance * Low standby current (typ.0.1uA) * Low static operational current * On-chip thermal shut down (TSD) with hysteresis SOP-8 „ ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing UMD9111L-S08-R UMD9111G-S08-R SOP-8 Tape Reel w w w . u n i s o n i c . c o m . t w 1 of 8 Copyright © 2018 Unisonic Technologies Co., Ltd QW-R109-041.a

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 P D=(TJ-TA)/θJA. W h e r e T J is junction temperature with the circuit working, and T A 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. „ THERMAL DATA PARAMETER SYMBOL RATINGS UNIT Junction to Ambient θJA 143 °C/W „ RECOMMENDED OPERATIONAL CONDITIONS (TA=25°C, unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Maximum Logic and Control Supply Voltage VCC 5.0 V Maximum Output Supply Voltage V DD 9.6 V Note: Logic control power supply V CC and power supply V DD are fully separate internally, and can supply electricity separately.

UMD9111 Preliminary CMOS IC „ APPLICATION INFORMATION 1. Baseline Mode a) Standby mode In standby mode, INA=INB=L. All internal circuits, in cluding 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 OU TA 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 th is point the motor drive end OUTB outputs high level, and the motor drive end OUTA outputs low level, then the motor drives the curr ent 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.
