ZHCSP41 January 2022 TPSM5D1806E
PRODUCTION DATA
The TPSM5D1806E is in active mode when VIN is above the turn-on threshold and the EN pin voltage is above the EN high threshold. Floating the EN pin allows the device to start-up when a valid input voltage is applied. This allows self start-up of the TPSM5D1806E when the input voltage is in the operation range of 4.5 V to 15 V. Connecting a resistor divider between VIN, EN, and AGND increases the UVLO threshold.
