DATASHEET ISL88705, ISL88706, ISL88707, ISL88708, ISL88716, FN8092 Rev 6.00 ISL88813 November 30, 2015 Designed with high reset threshold accuracy and low power Features consumption, the ISL88705, ISL88706, ISL88707, Fixed-Voltage Options Allow Precise Monitoring of +3.0V, ISL88708, ISL88716 and ISL88813 devices are +3.3V, and +5.0V Power Supplies microprocessor supervisors that are designed to monitor power-supply and battery functions in microprocessor Additional Voltage Monitor for Power-Fail Detection or Low-Battery Warning systems. They can help to lower system cost, reduce board space requirements and increase the reliability of systems. - Monitors Voltages Down to 1.25V - Adjustable Power-Fail Input Threshold These devices provide essential functions such as supply voltage supervision by asserting a reset output during Watchdog Timer Capability With 1.6s Time-out power-up and power-down as well as during brownout Both RST and RST Outputs Available conditions. An auxiliary voltage monitor is provided for 140ms Minimum Reset Pulse Width with Option to detecting power failures warning the system of low battery Customize Using an External Capacitor conditions or presence detection. In addition, an independent watchdog timer helps to monitor Manual Reset Input on all Devices microprocessor activity every 1.6s (typical). An active-low Reset Signal Valid Down to V = 1V DD manual reset is offered and reset signals remain asserted until V returns to proper operating levels. Accurate 1.8% Voltage Threshold DD Immune to Power-Supply Transients Users can increase the nominal 200ms power-on reset time-out delay by adding an external capacitor to the C POR Ultra Low 10A Maximum Supply Current at 3V pin on the ISL88707 and ISL88708.
