A1210/1/2/3/4 Continuous Time Hall Effect Latches, Allegro Microsystems
The Allegro Microsystems A1210/1/2/3/4 Hall-effect latches include a voltage regulator, Hall-voltage generator, small-signal amplifier, Schmitt trigger, and NMOS output transistor. The voltage regulator enables operation from 3.8 V to 24 V. On-board protection circuitry provides a ±30 V absolute maximum voltage rating for automotive and industrial motor commutation applications.
All devices in the family are identical except for magnetic switchpoint levels.
Available in a SOT23W, low profile surface-mount package or a three-lead ultramini SIP for through-hole mounting.
AEC-Q100 automotive qualified
Continuous-time operation
Fast power-on time
Low noise
Stable operation over full operating temperature range
Reverse battery protection
Solid-state reliability
