- (A1147 / A1148) Low Current Ultrasensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches
Description
A1147 and A1148 Low Current Ultrasensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches .
Features
* ▪ Chopper stabilization ▫ Low switchpoint drift over operating temperature range ▫ Low sensitivity to stress ▪ Factory programmed at end-of-line for optimized switchpoints ▪ On-chip protection ▫ Supply transient protection ▫ Reverse-battery protection ▫ On-board voltage regulator ▫ 3.5 to 24 V operaApplications
* these switches are utilized to sense seat track position, seat belt buckle presence, hood/trunk latching, and shift selector position. Two-wire unipolar switches, such as the A1147 and A1148, are particularly advantageous in price-sensitive applications because they require one less wire for operatA1147 Distributors
