FEATURES
- Bipolar Hall effect latch sensor - 3.5V to 20V DC operation voltage - Open collector pre-driver - 25mA output sink current - Chip power reverse-connection protection - Operating temperature: −40°C ~ +125°C - Package: SIP3, SOT23 GENERAL DESCRIPTION
An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. While the magnetic flux density (B) is larger than threshold Bop, the OUT pin turns off (High). If B removed toward Brp, the OUT pin is latched “off” state prior to B < Brp. When B < Brp, the OUT pin go into “ on ” state. APPLICATIONS
