PWM output with ±84 mT range
The DRV5057A3QDBZT is a single-axis Hall-effect sensor from Texas Instruments that outputs a PWM signal proportional to the magnetic field strength, with a sensing range of ±84 mT. The PWM output simplifies interface to a microcontroller's capture timer or digital input — no ADC channel needed, and the duty cycle carries the field reading directly. Bandwidth is 2 kHz, which covers most rotary position and linear displacement applications below that frequency.
Dual supply rails, SOT-23-3 footprint
Maximum supply current is 10 mA, and the output can sink or source up to 20 mA. Housed in a standard SOT-23-3 package (TO-236-3 / SC-59), it shares the same footprint as many other linear Hall sensors — a straightforward drop-in for BOM consolidation. The surface-mount package suits automated assembly and reflow profiles typical for small-signal passives.
