Part Number: TPS65721 Other Parts Discussed in Thread: MSP430F5528 , We are experiencing an issue where our devices will occasionally have a higher current draw (between .5 and 1.5 mA when normally 70 uA) after the voltage drops below ~2V, and then is brought…
Part Number: TPS65721 *This is for the TPS657201*
Hi,
My customer wants to switch the buck output to 3.3V instead of the default 1.85V. It looks like every time the battery is removed, the buck output will be reset to 1.85V.
We can write 3.3V to the…
Part Number: TPS65721 Hi,
Can you help me understand how to change the register settings of the TPS65721? Any and all details around this would be greatly appreciated.
Thank you.
Other Parts Discussed in Thread: TPS65721 Hello,
I've attached a image of the current PMU setupusing the tps65721 to generate 3.3V on the DCDC converter and then produce 1.8V on the LDO and I just wanted to verify that my design looks ok. In addition…
Other Parts Discussed in Thread: TPS65721 I am trying to find a reliable way to tell if a battery is detached using the TPS65721 while plugged in over USB. Right now I am using the comparator to see if the battery voltage is less than 2.2V (register 0x05…
Other Parts Discussed in Thread: TPS65721 We have 2 questions:
1) We see a large power dissipation jump from PFM to PWM, about 100mA in operation mode. What`s value that we shall see. Seems its too large.
On the data sheet (TPS65720m TPS657201m TPS657202…
Hi,
What is the best way to know when the battery voltage falls below a given threshold (and maybe get an interrupt from this event)?
On page 28 of the datasheet, it speaks about an internal battery voltage comparator, but the thresholds are selectable…

1. If PB_IN is applied during the operation? 2. Does PB_IN Timing starts again from the beginning?
3. How To Reset the TPS65721? Because the need to control the output of the DC/DC output and LDO output…
Other Parts Discussed in Thread: TPS65721 Hello
I had some basic question related to TPS65721 and I hope you could answer them. Please ignore if few question have been already answered in previous threads. 1. Can the MODE pin be left floating and the PWM…
