Part Number: TPS2HB50-Q1


Hi team,

My customer are using TPS2HB50AQPWPRQ1 and SCH as below.

Are there any risk if R10004 and R10005 not populated? Thanks

    Hi Xiaowei,

    It is highly recommended that the current limit is set externally using a resistor. The internal limits are designed for fail-safe cases (for example, the external resistor gets damaged), so the device can protect itself and is considered a fault for the device. If ILIM is connected to ground or left floating, the device will refer to the internal current limit. Also, shorting ILIM to VBB is not an option for configuring the current limit pin/feature correctly. 

    Thanks,
