The HA13557FH has the motor stop detector as shown hatching block. This function is monitoring
the situation of the motor while the motor is running by B-EMF sensing. If the motor will be caused a
misstarting up, the motor will be automatically restarted within 200 ms after the motor stopped. This
function increase the reliability for the motor starting up.

Operating voltage range is 10.2 V to 13.8 V.
Operating voltage range is 4.25 V to 5.75 V.
Applied to Pin 24, 25, 26, 28, 32, 33 and pin 38
Operating junction temperature range is Tjop = 0°C to +125°C.
ASO of upper and lower power transistor are shown below.
Operating locus must be within the ASO.
6. The OTSD (Over Temperature Shut Down) function is built in this IC to avoid same damages by
over heat of this chip. However, please note that if the junction temperature of this IC becomes
higher than the operating maximum junction temperature (Tjopmax = 125°C), the reliability of this
IC often goes down.
