Part Number: BQ25570 Other Parts Discussed in Thread: BQ25505 , BQ25504 Tool/software: We have an input current ranging from 5A to 300A. At 5A, a minimum of 70mW of energy is harvested. The harvested energy is used to charge a supercapacitor and then…
Part Number: BQ25505 Hi, The datasheet says that "When no input source is attached, the VSTOR node should be discharged to ground before attaching a storage element. Hot-plugging a storage element that is charged (for example, the battery protector PFET…
Part Number: BQ25505 Hi,
I will have the following questions:
1. The charger only looks at the voltages on VBAT_OV every 64ms that means the VRDIV node is monitored to samples and holds the VSTOR voltage.In addition to power consumption, does this situation…

Hi Team,
Customer now use BQ25505 in watch display. The BQ25505 is used as a relay boost for the solar panel to charge the watch battery.
The maximum voltage of solar energy is around 0.7V, and solar energy charges the battery through…
Part Number: BQ25505 This question refers to the BQ25505EVM. According to the User Guide (SLUUAA8A) there are some changes to Pin and Vin for cold start (this is not clear). Could you confirm the minimum input power and voltage for cold start with depleted…

This question refers to the BQ25505EVM. I connected my board to a DC supply and the minimum voltage and current for the circuit to start (Vstor from 0 to 4V) is 0.54V and 3.57 mA. This would equate to 1.92 mW which is orders of magnitude…
Part Number: BQ25505 Other Parts Discussed in Thread: BQ25570 Hi team,
One of the customer wants to evaluate BQ25505 for the design but EVM is not available on ti.com. Can you please suggest how to get an EVM for evaluation purpose?
Part Number: BQ25505 Other Parts Discussed in Thread: BQ25798 , BQ24210 I've been playing around with the BQ25505 for some time now and I get mixed results. I really like this device because of its multiplexing capability. I would like your thoughts…
Part Number: BQ25505
Note that R1 connections to Pin 11 and Pin 12 are reversed and have been modified on PCBA.
It seems that no matter what I do with the input voltages J1 to pin 2 and through L1 I cannot get the nVB_SEC_ON signal Pin 9 to go low.

Part Number: BQ25505
This question refers to the BQ25505EVM. I have been trying to use this board to harvest power from a 50uW, 100kOhm source. However, measurements seem to indicate that the board requires much more current and power than advertised…
