Part Number: BQ24133
Hi,
Something is wrong with my circuit.
Input voltage VIN=13V, set 3 battery output. The measured no-load output voltage is only 7.4V, and the measured voltage at pin 14 is 3.3V. Please help me review the problems in the circuit…
Part Number: BQ24133 We accidentally damaged the chip while using BQ24133. We test the damaged chip and find that it is VREF, SW, CELL, SRN pin abnormality.
In use, we plug in the battery first and then the main power supply. The lithium battery is 12…
Part Number: BQ24133 Hi
The customer design with bq24133, they set the cell to VREF, but the SW output voltage only 8.5V, and the STAT is blinking.
the schematic as below:
In 9.3.9, except that the delay of 1.5s has not been measured, it meets the r…
Part Number: BQ24133 Hello team,
I have a question about the internal circuit of BTST and REGN.
According to the block diagram, BQ24133 has built-in bootstrap diode. However, what is the meaning of the external diode from figure 10-5? How does it affect…
Part Number: BQ24133 Dear Expert
Connect to an external power supply of 15V and start the mainboard. The power consumption of the board is 141mA. Plug in an unfilled battery and use a multimeter to measure the changes in the high (3.3V) and low (0.019V…
Part Number: BQ24133 Hi,
In the below circuit, what happens when battery is disconnected and adapter is plugged in.
Would BQ24133 try to push out constant current into the system?
Part Number: BQ24133 Hi,
Going through the datasheet, we came across the below system example.
Can we use the following circuit with 2-cell..?
Also what happens if the cell is removed and the adapter is powered ON in this configuration....?
