Superior high temperature performance is possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device over-molding, temperature dependencies, and thermal stress. The device includes a voltage regulator, Hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a short circuit protected open-drain output to sink up to 25 mA. An on-board regulator permits operation with supply voltages of 2.5 to 22 V. The advantage of operating down to 2.5V is that the device can used in 2.5V applications or with additional external resistance in series with the supply pin for greater protection against high-voltage transient events. The CHA92X/CHI92X series is digital unipolar Hall switch. When the applied magnetic flux density exceeds the BOP threshold, the chip open-drain output goes low. The output stays low until the field decreases to less than BRP, and then the output goes to high impedance. The CHA92X/CHI92X also integrated internal clamps against supply/output transients; output short circuits protection; reverse battery conditions. Three package styles provide a magnetically optimized package for most applications, SOT-23, TO-92S and SOT-89. Each package type is lead (Pb) free (suffix, –T), with a 100% matte-tin-plated lead-frame. Page 1/15 PDF
