ZHCSLU8A September 2020 – October 2020 TPS51397A
PRODUCTION DATA
The TPS51397A has an overvoltage protection feature, which has the same implementation. When the output voltage becomes higher than 125% of the target voltage, the OVP comparator output goes high, and the output will be discharged and latched after a wait time of 120 μs. This function is a latching operation, so it needs to reset by EN going low or VCC power cycling.
