The A1201 offers a 10 G improvement in operate point, and the A1204 supports a more extensive range of switchpoints. Overall, the A120x family, produced with BiCMOS technology, consists of 12/12/2008 Allegro | Products | A1201, A1202, A1203, and A1204 Next-Generation Continuous-Tim... Page 2 of 3 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, Hallvoltage generator, small-signal amplifier, Schmitt trigger, and NMOS output transistor. The integrated voltage regulator permits operation from 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.
