S ingle Coil Hall Effec t IC with T hermal Lock
Protec tion and Auto-Restart
Features:
Operate from 2.4V to 15V supply voltage.
On-chip Hall sensor.
Internal bandgap regulator allows temperature compensated operations and a
wide operating voltage range.
Output sinking capability up to 450mA for driving large load.
Lower current change rate reduces the peak output voltages during switching.
Available in rugged low profile SIP-4L packages.
Built-in protection resistance for reverse power supply fault.
Built-in
thermal lock protection
and
auto-restart
function.
General Desc ription:
WSH420 is designed to integrate Hall sensor with two push-pull output drivers and
frequency generator together on the same chip, it is suitable for single coil DC
brushless motors. It includes a temperature compensated voltage regulator, a
differential amplifier, a Hysteresis controller, complementary bi-direction drivers for
sinking and driving large current load. An on-chip protection resistor is implemented
to prevent reverse power fault.And built-in
thermal lock protection
and
auto-restart
function will automatically shutdown power at 120
°
C to prevent the coils be damaged
during high temperature and auto-restart at 115
°
C. It can replace the function of lock
protection and auto-restart at low cost.
WSH420 are rated for operation over temperature range from
–
20
C to 85
C and
voltage ranges from 2.4V to 15V.
