Overview
Voltage monitoring IC for power supply voltage supervision in digital systems, operating over the industrial-grade standard temperature range. The TPAX809 generates a reset signal that asserts low when the system supply voltage drops below the threshold, and deasserts high at least 140ms after the supply voltage recovers above the threshold. The TPAX809 series supports any customer-specified detection voltage threshold. Seven standard industrial voltage monitoring thresholds are currently available, covering four supply voltage categories: 5.0V, 3.3V, 3.0V, and 2.5V. The TPAX809 features a push-pull output stage that drives the reset output high when the monitored voltage exceeds the threshold. Fast power supply transients, glitches, and noise are filtered internally to prevent false triggering, while correct output logic and all performance parameters are guaranteed even with supply voltages as low as 1.0V. The TPAX809 is available in a compact 3-pin SOT-23 package.
