Product Overview
The A3212ELHLT-T is a micropower ultra sensitive hall effect switch with latched digital output in 3 pin SOT2-3 package. Improved stability is made possible through chopper stabilization (dynamic offset cancellation) which reduces residual offset voltage normally caused by device over moulding, temperature dependencies and thermal stress. A 2.5V to 3.5V operation and unique clocking scheme reduce the average operating power requirements to less than 15μW with 2.75V supply. The A3212ELHLT-T includes hall voltage generator, small signal amplifier, chopper stabilization, latch and MOSFET output on a single silicon chip. Advanced BiCMOS processing is used to take advantage of low voltage and low power requirements, component matching, very low input offset errors and small component geometries.
- Small size, solid state reliability
- Supply current (IDD(AVG)) of 5.1μA at VDD = 2.75V
- 0.1% duty cycle
- Chopping frequency (fc) is 340KHz
- Superior temperature stability
- Extremely low switchpoint drift
- Insensitive to physical stress
- High ESD protection
- Easily assembly into applications due to magnetic pole independence
- Operating ambient temperature range from -40°C to 85°C
Applications
Sensing & Instrumentation, Consumer Electronics, Portable Devices
