TMR1302B
Description
The TMR1302B is a digital omnipolar magnetic switch that integrates TMR and CMOS technology in order to provide a magnetically triggered digital switch with high sensitivity, high speed, and ultra-low power consumption. It integrates a push-pull half-bridge TMR magnetic sensor and CMOS signal processing circuitry within the same package. Designed for use in applications that are both power-critical and performance-demanding, this device includes an on-chip TMR voltage generator for precise magnetic sensing, TMR voltage amplifier and parator, a Schmitt trigger to provide switching hysteresis for noise rejection, and CMOS push-pull output. An internal band gap regulator is used to provide temperature pensated supply voltage for internal circuits, and it allows a wide range of operating supply voltages. The TMR1302B draws only 1.5μA resulting in ultra-low power operation, additionally it has fast response, accurate switching points, excellent thermal stability, and immunity...
