高耐压双极锁存霍尔开关，兼容市面上大多数177

GENERAL DESCRIPTION

HS177 is an integrated Hall effect latched sensor designed for electronic commutation of
brush-less DC motor applications. The device is using HV BCD process includes an on-chip Hall
voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitttrigger to provide switching hysteresis for noise rejection, and open-collector output. An internalband-gap regulator is used to provide temperature compensated supply voltage for internal circuitsand allows a wide operating supply range.
If a magnetic flux density larger than threshold Bop, OUT is turned on(low). The output state isheld until a magnetic flux density reversal falls below Brp causing OUT to be turned off (high).

FEATURES
Temperature compensation
Wide operating voltage range
Open-Drain pre-driver
25mA maximum sinking output current.
SIP-3L TO-92S Package( Green and LeadFree )

Applications
Solid state switch
Handheld Wireless Handset Awake Switch
Lid close sensor for battery powered devices
Magnet proximity sensor for reed switchreplacement in low duty cycle application
