WSH520
Low voltage Single Coil Hall Effect IC with
Complementary Output Drivers
Features:
z
Operate from
1.8V
to 4.5V supply voltage.
z
On-chip Hall sensor.
z
Internal thermal compensation circuit enable operation in a wide range
temperature without loss of sensitivity.
z
Output sinking capability up to 200mA for driving large load.
z
Available in rugged low profile SOT-25 packages.
General Description:
WSH520 is designed to integrate Hall sensor with complementary output drivers on
the same chip, it is suitable for single coil DC brushless motors. It includes a
temperature compensated circuit, a differential amplifier, a Hysteresis controller,
complementary bi-direction drivers for sinking and driving large current load.
WSH520 are rated for operation over temperature range from –20
C to 75
C and
voltage ranges from 1.8V to 4.5V.
