Hi Star,
Weak battery threshold is USB BC2.1 legacy requirement that requires the charger to stop charge if the battery is above this threshold while in default (15 minute) mode. The assumption is that the host has not successfully powered up and enumerated…
Part Number: BQ24158 Other Parts Discussed in Thread: BQ24153A , I attempt to use bq24158 to charge Li-lon battery, Vfloat = 4.4V. When I try to modify the register data via the GUI tool BQ24153A_9 EVM, I setup Battery Regulation Voltage = 4.4V, Maximum…
Other Parts Discussed in Thread: BQ24153A , BQ24156A , BQ24158 Q: Once the device (BQ24153A, BQ24156A, BQ24158) exits the standard path on the operational flow chart (pg. 15 in datasheet) and enters the high impedance mode, how does one return the device…
Other Parts Discussed in Thread: BQ24153A , BQ24185 Is there such a thing? The end product is a universal li ion battery charger which also outputs 5V@500mah. Input Voltage Based DPM is required.
If not, what micro controller is suggested as host for…
Other Parts Discussed in Thread: BQ24153A , BQ24232 Hi all,
I'm trying to figure out a charger IC to use to charge my 3.7V 1000mAh lithium polymer battery via USB. I want it to recharge within a short time like 2-3 hours but the time is not too…
Q: What happens if VBUS
is applied, then removed and VSCOUT is at first above the VLOWV but then drains
below it? If I then reapply VBUS, will it start charging or will it stay in Hi
Z mode?
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
