TPS386596
SLVSA75A –JULY 2010–REVISED AUGUST 2015
TPS386596 Quad Reset Supervisor With Manual Reset Input
1 Features 3 Description
The TPS386596 device monitors four power rails and
1
• Four Channel Voltage Detector
asserts the RESET signal when any of the SENSE
• Threshold Accuracy: 0.25% (typ)
inputs drop below the respective thresholds. SVS-1
• Fixed 50-ms RESET Delay Time
can be used to monitor a 3.3-V nominal power supply
with no external components required. SVS-2, SVS-3,
• Active-Low Manual Reset Input
and SVS-4 are adjustable using external resistors
• Very Low Quiescent Current: 7 µA (Typical)
and can be used to monitor any power-supply voltage
• SVS-1: Fixed Threshold for Monitoring 3.3 V
higher than 0.4 V. All SENSE inputs have a threshold
accuracy of 0.25% (typical). The TPS386596L33 also
• SVS-2/3/4: Adjustable Threshold Down to 0.4 V
has an active-low manual reset (MR) that can assert
• Open-Drain RESET Output
the RESET signal as desired by the application. The
• Space-Saving, 8-pin MSOP Package
open-drain, active-low RESET output deasserts after
a fixed 50-ms delay.
2 Applications
The TPS386596 has a low quiescent current of 7 µA
• Notebook/Desktop Computers
(typical) and is available in a space-saving, 8-pin
• Industrial Equipment MSOP package.
• Telecom, Networking Infrastructure
