Part Number: TPS22946 Hi team,
Customer has 2pcs TPS22946 that has problem in below situation.
In customer design, when Vin=2.3V, ON=0V. when Vin=4.6V, ON=2.3V. Normal device can output when Vin increase. But there are 2pcs can't output when Vin increase…
Hello Kalin,
just found a conversation about problems with the TPS22946 which could be relevant to my situation and has probably a similarity.

Part Number: TPS22946 Hello,
I have a question about the footprint for the TPS22946 load switch presented in the datasheet versus the one available in the Ultra Librarian site.
In the datasheet of the TPS22946, the recommended pad diameter is 0.225 mm…
Part Number: TPS22946 Hello, I have a number of circuits using the TPS22946, and I see random startup failures on some but normal operation on others.
Tried many troubleshooting steps to see if I can get a circuit that fails to start to function properly…
Part Number: TPS22946 Serious problem here with TPS22946YZPR.
Randomly the chip does not start.
Happens on many device we tested.
There appears to be a relation with the time the input power was off.
We could reproduce this several times with power off…
Hi Shlomi,
Looking at the TPS22946 datasheet, the TPS22946 has a 435mA current limit during initial turn on. I've estimated your turn-on time to be ~100us from your graph. Please find the calculation for your inrush current below:
Iinrush = Cload…
Part Number: TPS22946 Hello,
We're using a large number of TPS22946 (280psc) to control power supply for level shifters in our signal multiplexer design. And we observe that some of the switches are not turning on once EN signal is applied. It happens…
Part Number: TPS22946 Other Parts Discussed in Thread: TPS22951 Hi all,
Do we have a similar component, with similar size, that switches at higher current?
The motor for the application is not yet defined, therefore the needed current might be higher. …
Other Parts Discussed in Thread: TPS22946 We are using the TPS22946 to switch +5Vdc to optical detector IC ( Iload=10mA )
We found out that the device does not start sometime ( very random ) !
The circuit is connected with 'CL' and 'ON' are tied to Vin…
