The device clears the TSHUT bit if the user reads the STATUS register when the junction temperature is below

the TSHUT threshold of 150°C (typical).

In a stacked configuration, in which all devices share a common enable signal, a thermal shutdown condition

in one device disables the entire stack. When the hot device cools down, the whole stack automatically starts

switching again.

7.3.17 Stacked Operation

The user can connect multiple devices in parallel in what is known as a "stack"; for example, to increase output

current capability or reduce device junction temperature. A stack comprises one primary device and one or more

secondary devices. During initialization, each device monitors the SYNC_OUT pin to determine if must operate

as a primary device or a secondary device:

• If there is a 47kΩ resistor between the SYNC_OUT pin and ground, the device operates as a secondary

device.

• If the SYNC_OUT pin is high impedance, the device operates as a primary device.

Figure 7-15 shows the recommended interconnections in a stack of two TPS6287x devices.
