| Description | |
| The TMR1368 is an omnipolar magnetic switch that integrates Tunnel Magnetoresistance (TMR) sensor and CMOS technology, developed for high-sensitivity, low-power, high-precision, and low-voltage applications. The TMR1368 combines a TMR magnetic sensor with CMOS integrated circuits, including a voltage generator, comparator, Schmitt trigger, and push-pull output circuit, allowing it to convert varying magnetic field signals into digital voltage signal outputs. The TMR1368 provides a temperature-compensated power supply via an internal voltage regulator and supports a wide operating voltage range. With low operating voltage, nA-level supply current, a 3 Hz switching frequency, and a wide operating temperature range, the TMR1368 is an ideal choice for many low-voltage, low-power, and high-performance applications. It is available in SOT23-3 package and DFN4L (1.6 mm × 1.6 mm × 0.5 mm) package. |  SOT23-3                         DFN4L |
