Part Number: BQ24316 Other Parts Discussed in Thread: BQ24090 Attached to this posting is snippet from the BQ24316 data sheet pertaining to the undervoltage lock-out feature for the IN pin. If lithium ion cell voltages are generally north of 3V and as…
Part Number: BQ24316 Hi,
About the device of BQ24316, I am confused about that if there is a surge, which is about 25V peak , with a very short time, will it trigger BQ24316 to protect? I want know what is the minimum duration of the surge voltage that…
Part Number: BQ24090 Other Parts Discussed in Thread: BQ24316 Attached to this posting is a schematic of a single cell Li-Ion charger. The charger contains BQ24090 supervised by BQ24316. Why did the circuit designer include a 555 timer that zeroes out…
Other Parts Discussed in Thread: BQ27531-G1 , BQ24316 , TPS5450 , BQ24195 Hello,
I am designing a TM4C123/129 based system that draws a maximum of 3A of intermittent current and about 250mA of constant current. I am using TPS5450 voltage regulator and…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
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…
