Part Number: TPS65721 Other Parts Discussed in Thread: BQ24071 , TPS65070 , TPS65217 Hi,
my question is the title of this post.
TPS65721 can be used to charge the battery and as a voltage regulator (DCDC o LDO) and use those voltages for my circuit (when…
Part Number: TPS65721 Other Parts Discussed in Thread: TPS7A05 , , We are currently looking into you PMU TPS65721, but I need a little more info on the internal LDO before we can make our choice. More specifically I need to know how it behaves under load…
Part Number: TPS65721 Hello,
We need to keep battery charger always disabled on TPS65721.
What is the best way to do this ? The battery is always connected
and the PMIC must work as normally (with AC adapter, etc) but never try to charge the batt.
Thank…
Part Number: TPS65721 Other Parts Discussed in Thread: , TPS65217 , TPS65218D0 My goal is to have DCDC1 turn off, once the battery has finished charging from AC (the AC will remain connected).
But I can't get DCDC1 to turn off if AC is live. Setup…
Part Number: TPS65721 Hello,
Is it mandatory to use the PB1 push press first and then activate HOLD_DCDC1/LDO lines (in this order) to keep powered on the buck and LDO in TPS65721 ?
I would like simply use a permanent switch ON-OFF connected between HOLD_DCDC1…
Part Number: TPS65721
Hi, I have 2 quick questions:
1. For setting the charge current the following formula is given in the datasheet.
It is clear that one factor of setting the charge current is the external resistor. But how do I set K_SET?
An…
Part Number: TPS65721 Other Parts Discussed in Thread: BQ27426 , MSP430FR5869 I have a project using the MSP430FR5869 paired with the TPS65721 and BQ27426. I'm trying to use the ACTIVE and PGOOD interrupts detect when external power is applied or removed…
Part Number: TPS65721 Hi,
I just wanted some clarification on the first power-on requirements in section 8.3.10.6.1. The first part says first powerup can be done by pulling PB_IN low or valid AC input:
This next section says that first power-on can…
Part Number: TPS65721 Hi,
What is the best way to reset the IC in case of lockup? Pushing the PB_IN will disable the LDO and DCDC, but is there any way to reset the charger portion or IC?
Thanks,
Josh
