TMR1201
TMR Bipolar Switch
General Description
The TMR1201 is a digital latching bipolar magnetic switch that integrates TMR and CMOS technology in order to provide a
magnetically triggered digital switch with high sensitivity, high speed, and 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 high
accuracy applications, 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 TMR1201 features accurate switching points, fast response, a wide operating
temperature range, and excellent ESD immunity. It is available in two packaging form factors: SOT23-3 (P/N TMR1201S), or
TO-92S (P/N TMR1201T).
