UMD9111 Datasheet | Unisonic Technologies

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 current, and ensures the circuit to operate stably for a long time. The circuit has a wide working voltage range, the maximum continuous 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 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℃) set by internal temperature protection circuit, the internal 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 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 anti-mon state conduction circuit. - Low output impedance - Low standby current (typ.0.1u A) - Low static operational current - On-chip thermal shut down (TSD) with hysteresis - ORDERING INFORMATION Ordering Number Lead Free Halogen Free UMD9111L-S08-R UMD9111G-S08-R Package SOP-8 CMOS IC SOP-8 Packing Tape Reel .unisonic..tw Copyright © 2023 Unisonic Technologies Co., Ltd 1 of 8 QW-R109-041.b - MARKING Preliminary - PIN CONFIGURATION CMOS IC - PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME VCC INA INB VDD OUTB AGND PGND...
