BQ24751ARHDR Frequently Asked Questions (FAQ)
-
A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the battery, and the power inductors should be placed close to the device. A thermal pad should be used to connect the device to the PCB.
-
The inductor value depends on the input voltage, output voltage, and output current. A good starting point is to use the inductor value calculation formula provided in the datasheet. The inductor value should be selected to ensure that the inductor current ripple is within 20-40% of the output current.
-
The BQ24751ARHDR can operate in ambient temperatures up to 105°C. However, the device's junction temperature should not exceed 125°C. The device's thermal performance should be evaluated using thermal simulation tools or thermal testing.
-
The BQ24751ARHDR has a built-in overcurrent protection feature. The OCP threshold can be set using an external resistor connected to the OCP pin. The device will shut down if the output current exceeds the set threshold.
-
Yes, the BQ24751ARHDR has a low quiescent current of 15 μA in shutdown mode, making it suitable for battery-powered devices. The device also has a low-power mode that reduces the quiescent current to 5 μA.
