High Temp. High Volt. Hall Effect Switch with RPP
AS443
The AS443 is a Hall-effect sensor unlatch for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, and a comparator to provide switching hysteresis for noise rejection, and an open-collector output pre-driver. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.
If a magnetic flux density (B) is larger than operation point (Bop), OUT will turn on (Low). If B<Brp, OUT will turn off (High). AS443 is rated for operation over temperature range from -40°C to +150°C and voltage range from 3.5V to 45V.
The devices are available in low profile SIP-3L packages.
