continuous-time devices that feature fast power-on time and low-noise operation. Device programming is
performed after packaging, to ensure increased switchpoint accuracy by eliminating offsets that can be induced by
package stress. Unique Hall element geometries and low-offset amplifiers help to minimize noise and to reduce the
residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.
The A120x Hall-effect bipolar switches include the following on a single silicon chip: voltage regulator, Hall-
voltage generator, small-signal amplifier, Schmitt trigger, and NMOS output transistor. The integrated voltage
regulator permits operation from 3.8 to 24 V. The extensive on-board protection circuitry makes possible a ±30 V
absolute maximum voltage rating for superior protection in automotive and motor commutation applications,
without adding external components. All devices in the family are identical, except for magnetic switchpoints.
The small geometries of the BiCMOS process allow these devices to be provided in ultrasmall packages. The
package styles available provide magnetically optimized solutions for most applications. Package LH is a SOT23W,
a miniature low-profile surface-mount package, while package UA is a three-lead ultramini SIP for through-hole
mounting. Each package is lead (Pb) free, with 100% matte tin plated leadframes.
