TPS5410-Q1 www.ti.com......................................................................................................................................................................................... SLVSA23 – SEPTEMBER 2009 The ENA pin has an internal pullup current source, allowing the user to float the ENA pin. If an application requires controlling the ENA pin, use open drain or open collector output logic to interface with the pin.
