Other Parts Discussed in Thread: TPS63031 , TPS3619 I have a problem using the PFI/PFO# function of the TPS3619-33. My schematic is shown here attached. This is part of a bigger schematic, all constructed on the same PCB. The R1/R2 resistors are intended…
Other Parts Discussed in Thread: TPS3619 , TPS63031 Hi!
Below you can see my design for a power supply module.
There are two possible input supply voltages : (1)V_EXT_SUPPLY and (2)VBAT. The (1) is supposed to be a regulated voltage of 3.3V and the VBAT…
Other Parts Discussed in Thread: TPS3619 My question is the following :
Are the logic outputs of TPS3619 (RESET# and PFO#) open-drain? Would I have problems in case I connected these output lines in a wired-or configuration with output lines of other…
Hello Ben-san,
Do you mean the 100nF leakage current for TPS3600Dxx, TPS3619/20, TPS3606, etc. is specified as battery supply current when VOUT=VDD?

Other Parts Discussed in Thread: TPS3620 , TPS3619 I don't know if my google foo is failing, but does TI have anything similar to the MAX690T?
I need to switch in a battery backup if the AC line goes away.
Thanks.
Other Parts Discussed in Thread: TPS3600 , TPS3619 , TPS3620 We look for the Battery backup IC.
For example TPS3617-50DGK.

Hi Lalit,
It if definitely possible to implement what you are proposing as long as you follow the sequence seen in the datasheet (e.g. TPS3619-33 under Battery Freshness Seal ) you should be able to implement this process using the GPIO in another device…
Hi ion george
I would like to recommend the TPS3619-33 for your application.
TPS3619-33 is our Battery Backup Switchover Voltage supervisor.

Other Parts Discussed in Thread: TPS63030 , TPS61220 Hi!
Attached you can find the circuit around the TPS63030. Its output voltage is configured at 3.0V. When the device is put in sleep mode, the output current drawn from the regulator is 30uA @ 3.0V,…
