This combination lowers system cost, reduces board space requirements, and increases reliability. Applying voltage to VCC 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 VCC detection circuitry protects the user’s 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, 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. + V3 Monitor Logic VTRIP3 V3FAIL VCC or V2MON* + VTRIP2 V2MON V2 Monitor Logic V2FAIL SDA WP Data Register Command Decode Test & Control Logic Fault Detection Register Status Register Watchdog and Reset Logic WDO MR SCL VCC (V1MON) + VCC Monitor Logic VTRIP1 Power on, Manual Reset Low Voltage Reset Generation RESET X40030/34 RESET X40031/35 LOWLINE 1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 | Intersil (and design) is a registered trademark of Intersil Americas Inc.
