DESCRIPTION

These devices combine three popular functions, Power-

on Reset Control, Supply Voltage Supervision, and Block

Lock Protect Serial EEPROM Memory in one package.

This combination lowers system cost, reduces board

space requirements, and increases reliability.

Applying power to the device activates the power-on

reset circuit which holds RESET/RESET active for a

period of time. This allows the power supply and oscilla-

tor to stabilize before the processor can execute code.

The device’s low V

detection circuitry protects the

user’s system from low voltage conditions by holding

RESET/RESET active when V

falls below a mini-

mum V

trip point. RESET/RESET remains asserted

until V

returns to proper operating level and stabi-

lizes. Five industry standard V

TRIP

thresholds are

available, however, Intersil’s unique circuits allow the

threshold to be reprogrammed to meet custom

requirements or to fine-tune the threshold in applica-

tions requiring higher precision.
