3.2.1 VOUT Short-to-VBAT Application

  • Application 1: Power off the power supply, then short CSN to VBAT. TPS25830, TPS25831-Q1, and TPS25840-Q1 do not support short-to-battery protection in this case.
  • Application 2: Short CSN to VBAT, then power on the power supply. TPS25830, TPS25831-Q1, and TPS25840-Q1 do not support short-to-battery protection in this case.
  • Application 3: Short CSN to VBAT and power on the power supply, then enable EN. TPS25830, TPS25831-Q1, and TPS25840-Q1 do not support short-to-battery protection in this case.
