| Description de l'article | Switch sensor / TMR1305 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 is designed for use in applications that are both power-critical and performance-demanding. It contains a push-pull half-bridge TMR magnetic sensor and cmos signal processing circuitry within the same package, including an on-chip TMR voltage generator for precise magnetic sensing, a TMR voltage amplifier and comparator plus a schmitt trigger to provide switching hysteresis for noise rejection, and cmos push-pull output. An internal band gap regulator is used to provide a temperature compensated supply voltage for internal circuits, permitting a wide range of supply voltages. The TMR1305 draws only 2µA resulting in ultra-low power operation. It has fast resp |
