Part Number: TPS3823 Hi,
I am using TPS3823A-33 in our product. we are giving 100msec pulse width on WDI pin.
All of sudden the TPS3823A-33 getting heat and reset latched to low. The pulse on WDI was continuous high. There is no short between pins
Part Number: TPS3823 Hello guys,
One of my customers uses TPS3823-50DBVT for their current mass-production.
Recently, they received PCN(PCN# 20230830002.3) which says TPS3823-50DBVT will be EOL. (TPS3823-50DBVR will be not EOL) At this moment, they have…

Hi expert,
TPS3823-Q1WDI working modes:
Use: external I/O
Unused:
Floating (high impedance): internal timer
Place a 1-kΩ resistor from WDI to ground: need BU to explain the working mechanism ( What is the operating mode that is…
Part Number: TPS3823 Hi team,
I see the datasheet that only max Ta is described, but no max Tj, so i want to know that what is the max Tj of the device?
Thanks!
