APS12205, APS12215, and APS12235: High-Temperature Hall-Effect Latches for Low Voltage Applications

Description

The APS12205, APS12215, and APS12235* Hall-effect sensor ICs are extremely temperature-stable and stress-resistant devices especially suited for operation over extended junction temperature ranges up to 175°C. Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress.

The single silicon chip includes: a Hall plate, small signal amplifier, chopper stabilization, Schmitt trigger, and a shortcircuit-protected open-drain output to sink up to 10 mA. A south pole of sufficient strength turns the output on; a north pole of sufficient strength is necessary to turn the output off. For applications requiring operation from greater than 5.5 V or operation directly from a battery, refer to the A1220, A1221, or A1223.

Two package styles provide a choice of through-hole or surface mounting. Package type LH is a modified 3-pin SOT23W surface-mount package, while UA is a three-pin ultramini SIP for through-hole mounting. Both packages are lead (Pb) free, with 100% matte-tin-plated leadframes.
