AX8401

AX8401 COMPLEMENTARY OUTPUT HALL EFFECT LATCH  GENERAL DESCRIPTION AX8401 is a single-digital-output Hall-Effect latch sensor for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, a comparator to provide switching hysteresis for noise rejection, and an output driver. An internal bandgap regulator provides a temperature compensated supply voltage for internal circuits and allows a wide operating supply range. When the magnetic flux density (B) is larger than operate point (Bop), output is switched on (OUT pin is pulled low). The output state is held on until a magnetic flux density reversal falls below Brp. When B is less than Brp, the output is switched off. The AX8401 is available in SIP-3L package.  FEATURES Bipolar Hall-Effect latch sensor 4.5V to 28V DC operating voltage 20mA output sink current Board Operating temperature range of -40°C to +125°C Green package: SIP-3L  BLOCK DIAGRAM VCC 1 VÛmw`RyÑb€ w.goftechm REG 3 + AMP OUT 2 GND 1/6 Axelite Confidential Materials, do not copy or distribute without written consent.
