    Part Number: BQ25620 The BQ2562x family of charger ICs can be configured to operate in a variety of ways via I2C communication. They can also operate in 'default mode' without host control. The BQ2562x family of devices does not have non-volatile…

  • [FAQ] BQ25620: How does QON pin function work and what is required hold low timing?

    Part Number: BQ25620 The QON pin on the BQ2562x family of devices has 2 functions, which are both controlled by pulling QON low for a certain amount of time. These 2 functions are exit ship mode (i.e. BATFET enable) and system power reset. The timing…

  • [FAQ] What is Latch up in CMOS Devices and How can Latch up Immune Multiplexers Improve System Reliability?

    What is Latch up? Latch-Up is a condition where a low impedance path is created between a supply pin and ground. This condition is caused by a trigger (current injection or overvoltage), but once activated, the low impedance path remains even after…
