These devices combine three popular funcTIons, PoweronReset Control, Supply Voltage Supervision, and BlockLock Protect Serial EEPROM Memory in one package.This combinaTIon lowers system cost, reduces boardspace requirements, and increases reliability.Applying power to the device acTIvates the power-onreset circuit which holds RESET/RESET acTIve for aperiod of time. This allows the power supply and oscillatorto stabilize before the processor can execute code.The device’s low VCC detection circuitry protects theuser’s system from low voltage conditions by holdingRESET/RESET active when VCC falls below a minimumVCC trip point. RESET/RESET remains asserted untilVCC returns to proper operating level and stabilizes. Fiveindustry standard VTRIP thresholds are available,however, Intersil’s unique circuits allow the threshold tobe reprogrammed to meet custom requirements or tofine-tune the threshold in applications requiring higherprecision.
