Part Number: BQ25150 Hi,
could you confirm that the 14 second watchdog works only when there is an external power source (VIN) BUT not the first time coming out from Ship Mode ?
In that case, is there another way to have also a watchdog when no VIN is…
Part Number: BQ25150 If the battery voltage is between 3V - 3.15V (Battery undervoltage Lockout Threhshold Voltage) the VDD remains ON if the device turns off by battery voltage drop below VBATUVLO. Do you have a solution?
Part Number: BQ25150 Similar to the first question about ship mode and register value retention - does low power mode allow for registers to retain their programmed values?
Part Number: BQ25150 Other Parts Discussed in Thread: BQ25121 , BQ25121A My team and I are currently looking at the BQ25150 as a charging solution for our high volume consumer electronic. We are noticing that entering and exiting ship mode causes all registers…
Part Number: BQ25150 In Section 9.4.2 of the BQ25150 datasheet, it states LP can be exited by driving the LP pin high OR Vin>Vuvlo. Later in the section it also states that MR can also cause the PMIC to transition from LP to Active Mode but as soon as…
Hi Stefan,
Stefan Lintner said: what is the ADC power consumption per channel?
In active battery mode, I found that, with 4.2V battery, enabling or disabling most of the ADC channels changed quiescent current consumption by approximately 1-2 uA, however…
Part Number: BQ25150 The datasheet implies that a host controller can initiate a power cycle: "A HW Reset may also be started by setting the HW_RESET bit. Note that during a HW reset , VDD remains on"
When I write a 1 to this bit I don't see…
In this design, its acceptable compromise that BQ25150 is in low power mode during startup and woken up with /LP or VIN since LS/LDO is not used straight after power up.
For future designs, possible solution could be resistor divider and/or RC delay…
Part Number: BQ25150 Hi Team,
in the DS on page 24 it says
The host may change the reset behavior at any time after MR going low and prior to the MR_HW_RESET timer expiring. It may not change it however from another behavior to a HW reset (Power Cycle…
Part Number: BQ25150 Sometimes when the power supply to the charger Vin is stopped, it is found that the charger Vin has a voltage output of 2.4V.
The probability of this happening is about 1/10. So what causes VIN to have voltage output?
