1 / 14 page  Preliminary Datasheet HIGH SENSITIVITY CMOS HALL-EFFECT LATCH AH921 Jun. 2010 Rev. 1. 0 BCD Semiconductor Manufacturing Limited 1 General Description The AH921 is a Hall-effect latch designed in mixed signal CMOS technology. It is quite suitable for use in automotive, industrial and consumer applications. Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device over-molding, temperature dependencies, and thermal stress. The device integrates a voltage regulator, Hall-voltage generator, small-signal amplifier, chopper stabilization, schmitt trigger, and is directly drivable by the output. An on-board regulator permits operation with supply voltage from 3.5V to 24V. The AH921 is available in TO-92S-3 and SOT-23-3 packages, which are optimized for most applications. Features • Wide Operating Voltage Range from 3.5 to 24V • Symmetrical Switch Points • Chopper-stabilized Amplifier Stage • Superior Temperature Stability • Compact Size • Built-in Pull-up Resistor • ESD Rating: 3500V (Human Body Model) Applications • Brushless DC Motor Commutation • Brushless DC Fan • Solid-state Switch • Revolution Counting • Speed Detection • High Sensitivity and Unconnected Switch Figure 1.
