7.3.5 Level-shifter Overcurrent Protection

The TPS65680 device protects its high-voltage output channels against overcurrent conditions in the PRESET and ACTIVE states. When an output channel switches, the device monitors the current flowing in the corresponding input supply pin (VGH, VGL1 or VGL2). If the current exceeds the user-programmed threshold, the device detects an overcurrent event.

When the TPS65680 device powers up it enters the PRESET state and enables each output channel one after the other. If an OCP event is detected, the device stops the output enable sequence, sets all the outputs to HiZ and enters the FAULT state.

In the ACTIVE state, the TPS65680 device counts OCP events in two counters: ALARM1 for clock channel OCP events and ALARM2 for control channel OCP events. If the number of events in either of these counters reaches the programmed maximum value, the device sets all the outputs to HiZ and enters the FAULT state. The ALARM1 and ALARM2 counters are reset at the start of each frame.

The OCP_FAULT1 and OCP_FAULT2 bits in the register indicate if the OCP event was caused by a clock channel or a control channel. To recover normal operation after an OCP event, you must apply a power cycle to the device.

A number of user-programmable registers control the OCP function. You can:

  • Use the register to enable and disable the OCP function for each supply pin
  • Use the , and registers to enable and disable the OCP function for each high-voltage output
  • Use the and registers to set the current sense delay
  • Use the register to program the OCP threshold
  • Use the register to select how the device reacts to an OCP condition
  • Use the and registers to select how many OCP events must occur before the device disables its outputs
