DRV5032-SOLAR-EVM
1
Overview
The DRV5032FB device is an ultra-low-power digital switch Hall-effect sensor, designed for the most
compact and battery-sensitive systems.
When the applied magnetic flux density exceeds the B
OP
threshold, the device output drives a low voltage.
The output stays low until the flux density decreases to less than B
RP
, and then the output either drives a
high voltage or becomes high impedance, depending on the device version. By incorporating an internal
oscillator, the device samples the magnetic field and updates the output at a rate of 20 Hz, or 5 Hz for the
lowest current consumption.
The device operates from a VCC range of 1.65 V to 5.5 V, and is packaged in a standard SOT-23.
