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).
