Motor Driver IC
http://onsemi.com
Overview
The STK984-091A-E is a hybrid IC designed to be used in Brush-less DC Motor.
Application
Industrial – Motor Drive
Features
FET can be driven (built-in pre-driver IC) by microcontroller output ( logic system).
Various protections (Overcurrent Protection, Over Temperature Protection, Low Voltage Protection, Over Voltage
Protection) are incorporated.
Intelligent DIAG Function that externally outputs each protection status, such as Overcurrent Protection, Over
Temperature Protection.
Protection functions can be reset by external inputs.

NOTE
1. A voltage overshoot with vibration will be occurred during a switching operation due to floating inductance of the
power source wiring connected between terminal +B1 and PG. In order that the voltage overshoot between +B1 and
PG, +B1 and each –UBW, each UVW and PG will not exceed its rating, please minimize wiring inductance by
shortening the wiring, also connect a snubber circuit close to between +B1 and PG terminals.
2. With the object of the overcurrent protection circuit fail-safe design, inserting a fuse in +B1 line is recommended.
3. There is a 100k (Typ) pull-down resister connected inside of the signal input terminal. However, in the case of
mounting a resister externally to reduce noise due to wiring, please satisfy the input voltage threshold of this
Hybrid-IC.
4. Terminal DIAG 1 and DIAG 2 are the open drain output configuration. Please pull up with 4.7k resister to 5V
power supply.
5. There is a 100k (Typ) pull-up resister connected inside of the RESET terminal. It operates normally in the open-
state. When the short-circuit protection operates and latches the output OFF, the latched output OFF can be released
by making RESET terminal Low and re-opened.
