Part Number: TPS65381A-Q1

Hello,

is there any clamping diode between VBAT Pin (Pin 29 / 1) and any Pin of Charge pump? (Pin 2, 3, 4).

thank you.

    Vorisek,

      I am not aware of any clamping diodes on the charge pump. There is a parasitic diode on the charge pump pins that will limit the charge pump to -0.3V. If you plan on using the reverse protection feature remember to include the 10k series resistor required in the data sheet to protect the charge pump from going negative.

    I will ask the designers about the clamping diodes, however at this time I would say no diode clamps..
