A1210, A1211, A1212, A1213, and A1214 Continuous-Time Latch Family FEATURES AND BENEFITS DESCRIPTION AEC-Q100 automotive qualified The Allegro A1210-A1214 Hall-effect latches are next generation replacements for the popular Allegro 317x and Continuous-time operation 318x lines of latching switches. The A121x family, produced Fast power-on time with BiCMOS technology, consists of devices that feature fast Low noise power-on time and low-noise operation. Device programming Stable operation over full operating temperature range is performed after packaging, to ensure increased switchpoint Reverse-battery protection accuracy by eliminating offsets that can be induced by package stress. Unique Hall element geometries and low-offset amplifiers Solid-state reliability help to minimize noise and to reduce the residual offset voltage Factory-programmed at end-of-line for optimum normally caused by device overmolding, temperature excursions, performance and thermal stress. Robust EMC performance The A1210-A1214 Hall-effect latches include the following on High ESD rating a single silicon chip: voltage regulator, Hall-voltage generator, Regulator stability without a bypass capacitor small-signal amplifier, Schmitt trigger, and NMOS output transistor. The integrated voltage regulator permits operation PACKAGES: from 3.8 to 24 V. The extensive on-board protection circuitry Not to scale 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. NOT FOR NEW DESIGN 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 3-pin SOT23W most applications. Package LH is an SOT23W, a miniature low- (suffix LH) profile surface-mount package, while package UA is a three-lead 3-pin SIP, 3-pin SIP, ultramini SIP for through-hole mounting. Each package is lead matrix HD style chopper style (Pb) free, with 100% matte-tin-plated leadframes.
