A1101, A1102, A1103, A1104, and A1106 Continuous-Time Switch Family FEATURES AND BENEFITS DESCRIPTION Continuous-time operation The Allegro A1101-A1104 and A1106 Hall-effect switches Fast power-on time are next generation replacements for the popular Allegro Low noise 312x and 314x lines of unipolar switches. The A110x family, Stable operation over full operating temperature range produced with BiCMOS technology, consists of devices that Reverse battery protection feature fast power-on time and low-noise operation. Device Solid-state reliability programming is performed after packaging, to ensure increased Factory-programmed at end-of-line for optimum switchpoint accuracy by eliminating offsets that can be induced performance by package stress. Unique Hall element geometries and low- Robust EMC performance offset amplifiers help to minimize noise and to reduce the High ESD rating residual offset voltage normally caused by device overmolding, Regulator stability without a bypass capacitor temperature excursions, and thermal stress. The A1101-A1104 and A1106 Hall-effect switches include Packages: the following on a single silicon chip: voltage regulator, Hall- 3-pin SOT23W (suffix LH) 3-pin SIP (suffix UA) 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 industrial motor commutation applications, without adding external components. All devices in the family are identical except for magnetic switchpoint levels. LH: A1101, A1102, The small geometries of the BiCMOS process allow these A1103, A1104, and devices to be provided in ultrasmall packages. The package A1106 styles available provide magnetically optimized solutions for UA: A1101, Not to scale UA: A1106 most applications. Package LH is an SOT23W, a miniature A1102, A1103, low-profile surface-mount package, while package UA is a and A1104 three-lead ultramini SIP for through-hole mounting. Each package is lead (Pb) free, with 100% matte tin plated leadframes.
