Where we won: TPS3780
High Accuracy, Dual Channel Voltage Detector
Application
SSD
•
Need to monitor multiple voltages in a system,
TPS3780 provides a small 1.5 x1mm package for
two channels
•
Low Iq consumption for portable applications
•
High Accuracy for positive and negative going
threshold to provide accurate voltage monitoring in
case of unplanned power down.
Why the customer preferred TI
•
High accuracy for positive and negative threshold :
1% over -40C to 125C
•
Business Results
Better than two one channel ICs or discrete
solution of compatator + reference IC.
•
Multiple hysteresis options for different
applications: 0.5%, 1%, 5%,10%
•
Low Iq : 2.2uA , Small package 1 x1.5mm
