APPLICATION INFORMATION
Thermal Shutdown
Undervoltage Lockout
Short Circuit Protection
SLVS976 – SEPTEMBER 2009.......................................................................................................................................................................................... www.ti.com
Figure 22. Control Block TPS65166
A thermal shutdown is implemented to prevent damages because of excessive heat and power dissipation. Once
a temperature of typlically 150°C is exceeded the device enters shutdown. It enables again if the temperature
drops below the threshold temperature of typically 135 °C and does normal startup.
To avoid mis-operation of the device at low input voltages an undervoltage lockout is included, which shuts down
the device at voltages lower than typically 8.0V.
The positive charge pump controller VONE will run with reduced current (typ. 50 A) and disables the boost
converter if short circuit is detected (FB4 falls below 100 mV). An exception is made at startup. If VONE has once
passed the short level threshold (FB4 is above 100 mV), the boost converter will not be disabled until Power
Good of VONE has been detected. In case there is already a short when the device is activated the charge pump
controller VONE will run with reduced current and the boost converter will not start until the short is removed and
VONE passes the short level threshold.
