UCC27284-Q1: Half-Bridge Gate Driver to Drive a High Side Back-to-Back N-MOSFETs

Part Number: UCC27284-Q1
Other Parts Discussed in Thread: UCC27284

Dear TI Team,

this is regarding an application circuit of : Half-Bridge Gate Driver to Drive a High Side Back-to-Back N-MOSFETs (in Common-Source Configuration)

When we disabled HI, we have following observations

  1. HO is taking ~200mS to become 0V even though Vgs becomes 0V in 1uS
  2. And MOSFET output is following HO.
