Input
The IMP6303 is a 4.0V power supply supervisor circuits optimized for low-
power microprocessor (μP), microcontroller (μC) and digital systems.
A reset signal is issued if the power supply voltage drops below a preset
reset threshold and is asserted for at least 140ms after the supply has
risen above the reset threshold. The IMP6303 has an active-low RESET
output that is guaranteed to be in the correct state for V
CC
down to 1.1V.
The reset comparator is designed to ignore fast transients on V
CC
.
Low supply current makes the IMP6303 ideal for use in portable and
battery operated equipment. The IMP6303 is available in a compact 3-pin
SOT23, TO-92 and 5 pin SOT23-5 packages.
