Part Number: TPS3619 Hello,
I would like to know if inrush current flows at VBAT pin when VDD to VBAT timing?
The customer sees VBAT voltage drops by inrush current of VBAT pin. I think VDD and VBAT are only switch so I think external circuit may do something…
Part Number: TPS3619-33-EP Other Parts Discussed in Thread: TPS3619 , TVS0701 Hi
Are there any recommended low leakage ESD protection solutions for the VBat pin of the TPS3619?
We are concerned with protecting the device when a user replaces the battery…
Part Number: TPS3619-33-EP Other Parts Discussed in Thread: TPS3620-33-EP , Hello,
I am interested in using the TPS3619-33-EP or TPS3620-33-EP as a battery backup IC. However, my idea was to connect the RESET output to a GPIO to indicate battery mode rather…
Part Number: TPS3619-33-EP Hi,
I am using this chip for RTC backup power. My design has to meet UL1642, according to which my circuit should limit the current flowing into the BR1225 cell to less than 3 mA after any single point of failure.
Given a scenario…
Other Parts Discussed in Thread: TPS3619 Dear, All
A customer is a circuit using TPS3619, and a problem occurs. Vout is not output at time when VDD did On/Off in short time. They suspect that "Battery Freshness Seal" function of TPS3619 worked.…
Hi Lalit,
Please refer to the Battery Freshness Seal section of the datasheet (page 10 of revision H). As long as this sequence is followed, you will enter the freshness seal mode.
Very Respectfully,
Ryan
Other Parts Discussed in Thread: TPS3619 Hi E2E Community! I have a scenario where I need not only one backup battery source, but two backup sources .
My question is what kind of issues can be expected if connecting two TPS3619 together like illustrated below…
e2e,
We have a customer that has questions about the TPS3619-33.
1) VOUT Batt drop, the datasheet only specs
Iout=.5mA, VBat=1.5 and Vout=Vbat-.05V
Iout=7.5mA, VBat=3.3 and Vout=Vbat-.113V
My specs are Iout=.1mA, VBAT=3, VDD=3.3V, -40C to 85C. What is…
Hi Ben, ok we are going to do some tests to confirm. I noticed on the datasheet pg3, that VIT is only specified for TPS3619-33 and TPS3619-50. Should the datasheet not say TPS36xx-33 and TPS36xx-50 to make it clear that this applies to both TPS3619 and…
Other Parts Discussed in Thread: MSP430F5529 , TPS3619 Hi all,
I am using MSP430F5529 (EVM) for my current project.also using TPS3619 in it. After connecting Coin cell battery reverse voltage generate at the 2 pin number of TPS3619-33 IC.
Please reply me…
