Supply Voltage Supervisor (SVS) [TPS65001 and TPS650061 Only]
The SVS is made up of 4 inputs and one output. The RST pin is an active low high impedance output. The MR
pin is an active low input, suitable for connecting to a push button circuit to allow manual reset generation. The
RSTSNS pin is an analog input pin used for voltage comparison. The TRST pin is connected to an external
capacitor, allowing the reset timing to be set in the application. The VINDCDC pin is the main supply input for the
control circuits and the switch mode converter.
Figure 28. SVS Block Diagram
Each input can individually trigger RST to go active. Table 1 outlines the paths to activate the reset.
