| Description de l'article | Switch sensor / TMR1302 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 comparator, 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 compensated supply voltage for internal circuits, and it allows a wide range of operating supply voltages. The TMR1302 draws only 1.5µA resulting in ultra-low power operation, ad |
