Functional Description
OSD
Output Stage Disable input. A High Level on this pin tristates the output stage. An internal weak pull-down resistor
to V_GND2 drives this input to Low state in case the pin is floating.
DACLP
Output pin used to disable the active clamping function of the booster.
DEBUG
Debug input pin. This pin is latched at power-up. When a High level is detected on this pin, the device enters a
special mode where it can be operated without SPI interface. This feature is for development purpose only. This
pin should normally be tied to V_GND2. An internal weak pull-down resistor to V_GND2 drives this input to Low state in
case the pin is floating.
IREF2
Reference input of the secondary chip. This pin shall be connected to V_GND2 via an external resistor.
VREG
Reference Output voltage. This pin shall be connected to an external capacitance to V_GND2.
NUV2
V_CC2 not valid notification signal (Open Drain). This signal drives a low level when V_CC2 is not valid or when the
internal 5V digital supply is not valid. When both supplies are valid, this pin is in high impedance state. This pin
shall be connected externally to a 5V reference with a pull-up resistance.
2.2.2.3 Pull Devices
Some of the pins are connected internally to pull-up or pull-down devices. This is summarized in Table 2-2.
