WSH411
Winson reserves the right to make changes to improve reliability or manufacturability.
Hall Effec t S ensor IC with T hermal Lock Protec tion
and Auto Restart Function
Features:
Operate from 2.8V to 20V supply voltage.
On-chip Hall sensor.
Internal bandgap regulator allows temperature compensated operations and a
wide operating voltage range.
High output sinking capability up to
500mA
for driving large load.
Lower current change rate reduces the peak output voltages during switching.
Available in rugged low profile SOT-25 , SIP-4L packages.
Built-in
FG
output.
Built-in protection diode for reverse power supply fault.
Built-in
thermal lock protection
and
auto-restart
function.
General Desc ription:
WSH411 is designed to integrate Hall sensor with complementary output drivers and
frequency generator together on the same chip, it is suitable for speed measurement,
revolution counting, positioning, and DC brushless motors. It includes a temperature
compensated voltage regulator, a differential amplifier, a Hysteresis controller, two
open-collector output drivers capable of sinking 1A 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.And built-in
thermal lock
protection
and
auto-restart
function is suitable for super high speed fan. It can replace
the function of lock protection and auto restart function. The power will be shutdown
automatically at 135
°
C to prevent the coils be damaged and atuo-restart after cooling
down.
The temperature-dependent bias increases the supply voltage of the hall plates and
adjusts the switching points to the decreasing induction of magnets at higher
temperatures. Subsequently, the open collector output switches to the appropriate state.
WSH411 are rated for operation over temperature range from
–
20
C to 100
C and
voltage ranges from 2.8V to 20V.
