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 VCC activates the power on reset circuit of X40034 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 VCC detection circuitry protects the users system from low voltage conditions, resetting the system when VCC falls below the minimum VTRIP1 point. RESET/RESET is active until VCC 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, Intersils 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.
