Current Sense
A sense FET monitors the current supplied to the load. The sense FET measures current more efficiently than
conventional resistance methods. When an overload or short circuit is encountered, the current-sense circuitry
sends a control signal to the driver. The driver in turn reduces the gate voltage and drives the power FET into its
saturation region, which switches the output into a constant-current mode and holds the current constant while
varying the voltage on the load.
Thermal Sense
The TPS206x implements a thermal sensing to monitor the operating temperature of the power distribution
switch. In an overcurrent or short-circuit condition the junction temperature rises. When the die temperature rises
to approximately 140
°C due to overcurrent conditions, the internal thermal sense circuitry turns off the switch,
thus preventing the device from damage. Hysteresis is built into the thermal sense, and after the device has
cooled approximately 10 degrees, the switch turns back on. The switch continues to cycle off and on until the
fault is removed. The open-drain false reporting output (OCx) is asserted (active low) when an overtemperature
shutdown or overcurrent occurs.
Undervoltage Lockout
A voltage sense circuit monitors the input voltage. When the input voltage is below approximately 2 V, a control
signal turns off the power switch.
