AH174
Inverted Output Hall Effect Latch High Temperature Features
Bipolar Hall effect latch sensor 3.5V operation voltage Open collector pre-driver 25mA output sink current Chip power reverse-connection protection Operating temperature: -40°C +125°C Package: SIP3, SOT23
AH174 single-digital-output Hall-effect sensor high temperature operation. device includes on-chip Hall voltage generator magnetic sensing, amplifier amplify Hall voltage, comparator provide switching hysteresis noise rejection, open-collector output pre-driver. internal bandgap regulator used provide temperature compensated supply voltage internal circuits allows wide operating supply range. While magnetic flux density larger than threshold Bop, turns (High). removed toward Brp, latched "off" state prior Brp. When Brp, into state.
