SNVSAH6C June 2018 – May 2021 LM2775-Q1
PRODUCTION DATA
The LM2775-Q1 provides two different output discharge modes upon entering a shutdown state (EN pin = '0') after running in the on state (EN = '1'). The first mode is high impendance mode (OUTDIS = '0'). In this mode, the output remains high even when the EN pin is driven low. This enables use in applications where the LM2775-Q1 output might be tied to a system rail that has another power source connected (USBOTG). When OUTDIS = 0, the output of the device draws a minimal current from the output supply (1.6 µA typical).
In Discharge Mode (OUTDIS pin = '1'), the LM2775-Q1 actively pulls down on the output of the device until the output voltage reaches GND. In this mode, the current drawn from the output is approximately 450 µA.
