  • Product introduction

The A3211 and A3212 integrated circuits are ultra-sensitive, pole-independent with latched digital outputsHall-effect switches。 These devices are ideal for the operation of battery-powered, handheld devices such as mobile and cordless phones, pagers, and PDAs. The 2.5 to 3.5 V operating voltage range and unique clocking method reduce average operating power requirements to less than 15 μW at 2.75 V supply voltage.

with othersHall-effect switchesThe difference is that as long as the ArcticorThe South Pole magnetic field is strong enough to turn on the output in the A3212, and when there is no magnetic field, the output stops. The A3211 provides a reverse output. Pole independent and minimal power requirements allow these devices to be easily swapped with reed switches, providing greater reliability and ease of fabrication, reducing signal conditions.

Stabilization chopping (dynamic offset cancellation) improves stability and reduces residual offset voltages typically caused by device overmolding, temperature dependence, and thermal stress.

The device concentrates a Hall generator, small signal amplifier, chopper-stabilizing feature, latching, and MOSFET output on a single silicon chip. Use advanced BiCMOS processes to achieve low voltage and power requirements, component matching, extremely low input deviation errors, and small component geometries.

Four package types provide magnetically optimized solutions for most applications. Miniature low profile surface mount package types EH and EL (0.75 and 0.50 mm above level) are Pb-free, LH is a three-pin low-profile SMD, and UA is a three-pin SIP for via mounting. The package is lead (suffix –T) and the leadframe is 100% matte tin plating.
