TIDRV5032FBLPGM
Overview
The DRV5032FBLPGM is an ultra-low-power digital omnipolar Hall effect switch designed for battery-critical applications. It operates on a wide supply voltage range of 1.65V to 5.5V and consumes an average quiescent current of only 0.69 microamps at 3V. The device features a push-pull output and triggers on either a north or south magnetic pole, making it ideal for position sensing in power-constrained environments.
Why Choose This Part
The primary advantage of this sensor is its exceptionally low 0.69 microamp power consumption, which allows for multi-year operation from a small coin cell. Its omnipolar sensitivity simplifies mechanical assembly by responding to either magnetic pole, while the push-pull output eliminates the need for an external pull-up resistor. The through-hole TO-92-3 package also provides ease of mounting in industrial or mechanical assemblies where PCBs are not flush against the sensing area.
Applications
Key Specifications
Getting Started
To evaluate this sensor, provide a stable supply between 1.65V and 5.5V and bypass VCC with a 0.1 microfarad ceramic capacitor. Since it is a push-pull device, the output can be connected directly to a high-impedance GPIO pin on a microcontroller. Use a magnet with a field strength exceeding the 4.8mT trip point to trigger the output change.
