Low Profile (1mm) SOT-23 (ThinSOT TM ) Package
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. V CC = V1 for LTC2903-D1 and
LTC2903-E1. The RST output is guaranteed to sink at least
5 μ A (V OL = 0.15V) for V CC 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.
