Part Number: TPS3898 Hello,
Looking at the device datasheet, it looks like the difference between TPS3898A and TPS3898P is the enable delay. The TPS3898P has a default delay, which cannot be adjusted. The TPS3898A delay can be adjusted by an extra capacitor…
Part Number: TPS3898 Other Parts Discussed in Thread: TPS62A01 , , TPS3703 Hi Team
My customer is using TPS62A01 with 3.3Vin and 1.1Vout, and is currently looking for a supervisor IC solution.
Their requirement is to latch the sense-out after the voltage…
Part Number: TPS3898 Hi,
I need a delay time of 1 second ( -> CT = 0.25 µF) and everytime the SENSE voltage falls below V IT- I have to be sure that the capacitor is fully discharged within 10 ms.
Will the CT capacitor be actively discharged when…
Part Number: TPS3898 Other Parts Discussed in Thread: TPS3840 Hello,
the TPS3898 is rated for 7V max. is there an equivalent part with active low enable and active low output which is rated for atleast 10V or more? it will be great if the part has adjustable…
Part Number: TPS3898 Hi Team,
Customer put total 1.47uF (1uF+0.47uF) at CT pin.
Based on calculation, the delay should be 1.47 * 4 s + 40us ~ 5.88s
But actual time delay measurement is about 1s.
Is the calculation correct?
Any tips we can check with customer…
Part Number: TPS3898 Hi there,
I can't find the max delay time in the datasheet. Does TPS3898A support a delay time up to 1 sec? thank you
regards,
Kevin
Part Number: BQ24780S Other Parts Discussed in Thread: TPS3898 , BQ24780 Hi TI Teams,
We have some question about the application of BQ24780S when the battery pack does not have a BATPRES output pin. We have found a post about battery packs without BATPRES…
Other Parts Discussed in Thread: TPS3808 Hi TI,
In my design , battery as input supply 3AA battery i.e 4.5V i want to rise an alarm when battery below 20 or 40 % it varies as per the design and ouput is given to GPIO of MCU . i would like to know from…
Roy,
1: could we adjust the tMR_bar_w from using external circuit?
Answer: tMR_bar_w is caused by the user because /MR is an input. In the above diagram, t_PD(/MR) is fixed, and t_D(/MR) is programmable with capacitor
2:
do we have the reset IC which has…
David,
1)
To start, it is very important to note that ENABLE and MR are inverses. RESET and SENSE OUT are also inverses. This means active-low RESET is the same function as active-high SENSE OUT. Active-low MR is the same as active-high ENABLE. You can…
