Monitoring

Low Supply Current: 20µA Typical

200ms Reset Time Delay

Active Low Open-Drain RST Output

Power Supply Glitch Immunity

Low Profile (1mm) SOT-23 (ThinSOT

) 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

) is generated from the greater

voltage on the V1, V2 inputs. V

= V1 for LTC2903-D1 and

LTC2903-E1. The RST output is guaranteed to sink at least

5µA (V

= 0.15V) for V

down to 0.5V and will typically

conduct current down to 0V. Quiescent current is 20µA

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.
