DESIGN FEATURES Programmable Quad Supervisors
Offer Unparalleled Flexibility for MultiVoltage Monitoring Applications
by Bob Jurgilewicz Introduction
Three new power supply supervisors
improve system reliability by offering
more accurate reset thresholds than
other supervisors on the market. They
also save design time, production
costs and board space with easy-touse, flexible interfaces and a low
external parts count.
The LTC2900, L TC2901 and
LTC2902 quad supervisors can simultaneously monitor four supply
voltages with 1.5% threshold accuracy over temperature. Each part
offers 16 user-selectable four-voltage
combinations from the following: 5V,
3.3V, 3V, 2.5V, 1.8V, 1.5V, +ADJ and
вЂ“ADJ. A simple external resistor
divider performs single-pin programming, eliminating the need to qualify,
source and stock different part num-5V
