LTC2905CTS8

The LTC2905CTS8 is a kind of dual supply monitor. It is designed for systems with two supply voltages. The device provides a precise, space-conscious and micropower solution for supply monitoring. The typical applications include desktop and notebook computers, handheld devices, network servers and core, I/O monitor.

There are some features of LTC2905CTS8. (1)monitors two inputs simultaneously; (2)nine threshold combinations; (3)three supply tolerances (5%, 7.5%, 10%); (4)guaranteed threshold accuracy: ±1.5% of monitored voltage over temperature; (5)internal VCC auto select; (6)power supply glitch immunity; (7)low dropout operation: 100% duty cycle; (8)0.8 V reference allows low output voltages; (9)adjustable reset time delay; (10)open drain RST output; (11)guaranteed RST for V1 1 V or V2 1 V; (12)low profile (1mm) SOT-23 (ThinSOTTM) and plastic (3mm x 2mm) DFN packages.

What comes next is the absolute maximum ratings of LTC2905CTS8. (1):V1, V2 (terminal voltage) is from -0.3 to 7 V; (2):S1, S2, TOL (terminal voltage) is from -0.3 to VCC+0.3 V; (3):RST (terminal voltage) is from -0.3 to 7 V; (4):TMR (terminal voltage) is from -0.3 to 7 V; (5): operating temperature range is from 0 to +70; (6):lead temperature (soldering, 10 seconds) is 300; (7):storage temperature range is from -65 to 150.
