TIDRV5032FCDBZR
Overview
The DRV5032FCDBZR is an ultra-low-power digital omnipolar Hall effect switch designed for battery-operated systems. It operates across a wide 1.65V to 5.5V supply range and features an open-drain output that simplifies interfacing with various logic levels. The device triggers on either a North or South magnetic pole, providing a consistent digital low output when a magnetic field exceeds the 4.8mT trip point.
Why Choose This Part
The primary advantage is its exceptional power efficiency, consuming a typical sleep current of only 1.6uA. Its omnipolar sensing capability removes the need for specific magnet orientation during assembly, reducing manufacturing complexity. Additionally, the open-drain output allows for flexible voltage translation when connecting to microcontrollers operating on different power rails.
Applications
Key Specifications
Getting Started
To evaluate this sensor, engineers can use the TI DRV5032-SOLAR-EVM or connect the SOT-23 package directly to a microcontroller GPIO with an external pull-up resistor. Ensure a 0.1uF ceramic bypass capacitor is placed close to the VCC pin for stable operation. Since the output is open-drain, the pull-up resistor value should be chosen based on the desired signal rise time and power constraints.
