A1212LUA-T¼¼Êõ²ÎÊýÏê½â£º
The A1210-A1214 Hall-effect latches 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 ¡À30 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.
