Part Number: TPS65721 Here is a schematic for my power management system. Lipo pack is 4.2v, charging is done via usb adapter. Every time i disconnect the power cable, module changes CHGSTATE firstly to CH_SLEEP, then to CH_RESET. RESET pin is always…
Part Number: TPS65721 Hello
We want to use tps65721 in our future products. Our main goal is powering a wearable device that feeds from a rechargable li-ion battery. We know that the device can be turn on/off by writting on the hold-dcdc and hold…
Part Number: TPS65721 Other Parts Discussed in Thread: BQ27426 Hi,
The part TPS65721 will be able to provide status of battery during charging and during field use.

Part Number: TPS65721 Other Parts Discussed in Thread: TPS65720 Hi!
I faced with very strange error during continuous reading (more of 1 register data) from TPS65721.
My solution:
CPU: STM32F103CBTX
IDE: STM CubeIDE
Library: STM HAL library…
Part Number: TPS65721 Hello. The issue stands and i'm quite lost. THRESHOLD connected directly to the DCDC1 output (3.3 V, tested and works as intended), without voltage dividers (pin connected directly to DCDC1 via 499KOhm resistor).
After connection…
Part Number: TPS65721 Hello,
Were are using the TPS65721 for the first time in our project and we need to charge a LIPO battery with it. For now, we are not interested by the DC/DC, LDO or GPIOs functions.
We have developed a small PCB to test the…
Part Number: TPS65721 Hi,
My device is going fault state during charging, it is not consistent but it occurs in every ~50 charge cycles. it recovers back once i give a device reset and it is not repeating for next few days.
I am reading the charge…
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…
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…
Part Number: TPS65721 In implementing the circuit as shown in the development kit, when charging only (DC/DC and LDO are off), I can only get 120 mA going into the battery. (5V, 2.5A wall-mount power supply)
When operating, I can get some current going…
