Description

The X40030, X40031, X40034, X40035 combine power-on reset control, watchdog timer, supply voltage supervision, second and third voltage supervision, and manual reset, in one package. This combination lowers system cost, reduces board space requirements, and increases reliability.

Applying voltage to V_CC activates the power on reset circuit which holds RESET/RESET active for a period of time. This allows the power supply and system oscillator to stabilize before the processor can execute code.

Low V_CC detection circuitry protects the user's system from low voltage conditions, resetting the system when V_CC falls below the minimum V_TRIP1 point. RESET/RESET is active until V_CC returns to proper operating level and stabilizes. A second and third voltage monitor circuit tracks the unregulated supply to provide a power fail warning or monitors different power supply voltage. Three common low voltage combinations are available, however, Intersil's unique circuits allows the threshold for either voltage monitor to be reprogrammed to meet specific system level requirements or to fine-tune the threshold for applications requiring higher precision.
