Winson, 2005/9/23 1
S ingle Coil Hall Effec t IC with T hermal Lock
Protec tion and Auto-Restart
Features:
Operate from 2.8V to 14V supply voltage.
On-chip Hall sensor.
Internal bandgap regulator allows temperature compensated operations and a
wide operating voltage range.
Output sinking capability up to 350mA for driving large load.
Lower current change rate reduces the peak output voltages during switching.
Available in rugged low profile SIP-4L,SIP-5L and SOT-25 packages.
Built-in Frequency Generator.
Built-in protection diode for reverse power supply fault.
Prevent the fail situation during lock status or high temperature
Built-in
thermal lock protection
and
auto-restart
function.
General Desc ription:
WSH42FB 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 and an open-collector frequency generator
capable of sinking 10mA current load. An on-chip protection diode is implemented to
prevent reverse power fault. It also includes coil parts.
You can eliminate all the
external components for the function of FG and reverse protection diode.
And
built-in
thermal lock protection
and
auto-restart
function will automatically shutdown
power at 110
°
C to prevent the coils be damaged during high temperature and
auto-restart at 105
°
C. It can replace the function of lock protection and auto-restart at
low cost.
WSH42FB are rated for operation over temperature range from
–
20
C to 90
C and
voltage ranges from 2.8V to 14V.
