DRV5032 Digital-Switch Hall Effect Sensors

Texas Instruments offers the DRV5032 ultra-low-power 1.65 V to 5.5 V Hall effect switch sensors

Image of Texas Instruments' DRV5032 Digital-Switch Hall Effect SensorsTexas Instruments' DRV5032 device is an ultra-low-power digital-switch Hall effect sensor, designed for the most compact and battery-sensitive systems. The device is offered in multiple sampling rates, output drivers, and packages to accommodate various applications.

When the applied magnetic flux density exceeds the BOP threshold, the device output drives a low voltage. The output stays low until the flux density decreases to less than BRP, 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. Omnipolar and dual-unipolar magnetic responses are available.

The device operates from a VCC range of 1.65 V to 5.5 V, and is packaged in a standard SOT-23 and small X2SON.

Features
  • Industry-leading ultra-low-power consumption
    • 5 Hz version: 0.54 µA with 1.8 V
    • 20 Hz versions: 1.6 µA with 3 V
  • 1.65 V to 5.5 V operating VCC range
  • Magnetic threshold (typical BOP):
    • 3 mT, high sensitivity
  • Omnipolar and dual-unipolar options
  • 20 Hz and 5 Hz sampling rate options
  • Open-drain and push-pull output options
  • SOT-23 and X2SON package options
  • -40°C to +85°C operating temperature range
Applications
  • Battery-critical position sensing
  • Electricity meter tamper detection
  • Cell phone, laptop, or tablet case sensing
  • E-locks, smoke detectors, appliances
  • Medical devices, IoT systems
  • Valve or solenoid position detection
  • Contactless diagnostics or activation
