Junction Temp
Output pin of the low side gate driver. Connect directly to the respective gate of an external N-
channel MOSFET.
Output pin of the high side gate driver. Connect directly to the respective gate of an external N-
channel MOSFET.
Lower supply rail for the high-side gate driver (GHx). Connect this pin to the switching node at
the junction between the two external power MOSFETs and the inductor. These pins are also
used to measure voltage drop across bottom MOSFETs in order to provide output current
information to the control engine.
High side driver supply pin(s). Connect BST to an external boost diode and a capacitor as
shown in the front page diagram. The high side driver is connected between the BST pin and LX
pin.
These pins can be configured as inputs or outputs to implement custom flags, power good
signals and enable/disable controls. A GPIO pin can also be programmed as an input clock
synchronizing IC to external clock. Refer to the “GPIO Pins” Section and the “External Clock
Synchronization” Section for more information.
I
functions in applications when I
Output of the Standby LDO. It can be configured as a 5V or 3.3V output. This pin should be
bypassed with a minimum of 2.2uF.
If ENABLE is pulled high, the chip powers up (logic reset, registers configuration loaded, etc.).
If pulled low for longer than 100us, the XRP7714 is placed into shutdown.
