UMD9112 CMOS IC
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.
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

UMD9112 CMOS集成電路
電動玩具直流電機驅動電路

描述

UTC UMD9112是專為低壓操作系統設計的單通道玩具直流電機驅動的集成電路。它具有H橋驅動器,並使用具有低輸出電阻的PMOS和NMOS功率晶體管。低導通電阻保證了電路在連續電流下工作時消耗更低的功率,保證了電路長時間穩定工作。
UTC UMD9112具有片內溫度保護功能。低內阻負載電機堵轉時,UTC UMD9112輸出電流瞬間增大,電路功耗急劇上升,芯片溫度飆升。但是,當芯片溫度超過內部溫度保護電路設定的最高溫度點(一般為150℃)時,內部電路會關斷UTC UMD9112的片內功率開關管,同時關斷負載電流,防止安全隱患過溫引起的塑料封裝冒煙、起火等危險。只有在確認電路已恢復到安全溫度後,才能允許片上溫度遲滯電路重新控制電路。

特徵
  • 內部 PMOS/NMOS 電源開關的 H 橋驅動器
  • 可實現負載電機4種功能(前進、後退、待機、制動)
  • 低輸出阻抗
  • 低待機電流(典型值 0.1μA)
  • 低靜態工作電流 (typ.300μA, VCC=3V)
  • 具有遲滯的片上熱關斷 (TSD)
