SNVSD07 October 2025 LM251772-Q1
PRODUCTION DATA
The LM251772-Q1 features a internal output discharge circuit.
The discharge strength is configured with the register DISCHARGE_STREGTH (see MFR_SPECIFIC_D2 Register Field Descriptions) to achieve different slew rates of the output voltage while discharging. The sequence is configured with the registers DISCHARGE_CONFIG0 and DISCHARGE_CONFIG1 in MFR_SPECIFIC_D2 Register Field Descriptions.
The register FORCE_DISCH in USB_PD_CONTROL_0 Register Field Descriptions forces the discharge circuit to be enabled or disabled and overwrites the sequence settings.
