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 openstate. 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.
