A3251 Description
The A3250 and A3251 are field-programmable, chopperstabilized, unipolar Hall-effect switches designed for use in high-temperature applications. These devices use a chopper-stabilization technique to eliminate offset inherent in single-element devices. The A3250 and A3251 are externally programmable devices.
A3251 Key Features
- Chopper stabilization for stable switchpoints throughout operating temperature range
- Externally programmable operate point (through VCC pin)
- On-board voltage regulator for 4.2 V to 24 V operation
- On-chip protection against: ▫ Supply transients ▫ Output short-circuits ▫ Reverse-battery condition
