2.5V unipolar Hall switch with 24mT trip threshold
The Texas Instruments DRV5023BIQLPGM is a unipolar Hall-effect switch that responds to a south-pole magnetic field, with a 24mT operate point and a 3mT release point. It operates from a 2.5V supply rail and delivers an open-drain output rated for 30mA continuous sink current, with a typical switching current of 2.7mA.
Through-hole TO-92 package and output stage
Housed in a 3-pin TO-92 through-hole package, the DRV5023BIQLPGM is supplied in cut tape or tape-and-box formats for pick-and-place or hand-insertion assembly. The open-drain output allows the switch to interface directly with microcontrollers or logic inputs; an external pull-up resistor to the desired logic rail sets the output high level.
