AX8401
AX8401 is COMPLEMENTARY OUTPUT HALL EFFECT LATCH manufactured by AXElite.
AX8401 PLEMENTARY 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 parator to provide switching hysteresis for noise rejection, and an output driver. An internal bandgap regulator provides a temperature pensated 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 20m A output sink current Board Operating temperature range of -40°C to +125°C Green package: SIP-3L
