LTC2906/LTC2907  
Precision Dual Supply Monitors  
with One Pin-Selectable Threshold  
and One Adjustable Input  
U
FEATURES  
DESCRIPTIO  
The LTC®2906/LTC2907 are dual supply monitors in-  
tended for systems with multiple supply voltages. The  
dual supply monitors have a common reset output with  
delay (200ms for the LTC2906 and adjustable using an  
external capacitor for the LTC2907). These products pro-  
vide a precise, space-conscious and micropower solution  
for supply monitoring.  
■
Monitors Two Inputs Simultaneously  
■
Three Threshold Selections for 5V, 3.3V or 2.5V  
Supplies  
■
Low Voltage Adjustable Input (0.5V)  
■
Three Supply Tolerances (5%, 7.5%, 10%)  
■
Guaranteed Threshold Accuracy: ±1.5% of  
Monitored Voltage Over Temperature  
■
Internal VCC Auto Select  
Power Supply Glitch Immunity  
The LTC2906/LTC2907 feature a tight 1.5% threshold  
accuracy over the whole operating temperature range  
and glitch immunity to ensure reliable reset operation  
without false triggering. The open drain RST output state  
is guaranteed to be in the correct state for V1 and/or VCC  
down to 1V.  
■
■
200ms Reset Time Delay (LTC2906 Only)  
■
Adjustable Reset Time Delay (LTC2907 Only)  
■
Open Drain RST Output  
■
Guaranteed RST for V1 ≥ 1V or VCC ≥ 1V  
Low Profile (1mm) SOT-23 (ThinSOTTM) and  
■
The LTC2906/LTC2907 also feature one adjustable input  
with a nominal threshold level at 0.5V, another input with  
three possible input threshold levels, and three supply  
tolerances for possible margining. These features provide  
versatility for any kind of system requiring dual supply  
monitors. Two three-state input pins program the thresh-  
old and tolerance level without requiring any external  
components.
