Low Profile (1mm) SOT-23 (ThinSOT

The LTC
2903-1 monitors up to four supply voltages. The
common reset output remains low until all four inputs
have been in compliance for 200ms. Voltage thresholds
maintain
±
1.5% accuracy over temperature (with respect
to the monitored voltage). The LTC2903-1 features an
open-drain RST output with a weak internal pullup.
Internal supply voltage (V
CC
) is generated from the greater
voltage on the V1, V2 inputs. The RST output is guaranteed
to sink at least 5
μ
A (V
OL
= 0.15V) for V1, V2 or V3 down
to 0.5V and will typically conduct current down to 0V.
Quiescent current is 20
μ
A typical, making the LTC2903-1
ideal for power conscious systems. The LTC2903-1 is
available in a 6-lead low profile (1mm) SOT-23 package.
