The from Products is a microprocessor µP supervisory reset circuit with edge triggered, one shot manual reset in 4 pin SOT143 package. The µP supervisory circuits monitor single power supply voltages from +1.8V to +5V and assert a reset if the supply voltage drops below its preset threshold. A variety of factory-trimmed threshold options accommodate different supply voltages and tolerances eliminating external components. The factory set thresholds range from +1.575V to +4.625V to monitor +5V, +3.3V, 3V, 2.5V and 1.8V supplies with various tolerances. Reset timeout periods of 150ms min and 1200ms min are available to accommodate different µP platforms. It is ideally used at cell phones/PDAs, embedded control systems, industrial equipment, automotive products, portable/battery-powered equipment, medical devices, DSL modems, MP3 players, GPS systems and digital cameras.
