Functional Description

GATE

Input pin used to monitor the IGBT gate voltage.

OSD

Output Stage Disable input. A High Level on this pin tristates the output stage. An internal weak pull-down

resistor to VGND2 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 VGND2. An internal weak pull-down resistor to VGND2 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 VGND2 via an external resistor.

VREG

Reference Output voltage. This pin shall be connected to an external capacitance to VGND2.

NUV2

VCC2 not valid notification signal (Open Drain). This signal drives a low level when VCC2 is below VUVLO2L 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 to ensure level read-out over the

respective register. The pin can be connected also to respective ground potential (This enables usage together

with OSD pin).

AMCLP

Active Miller Clamping External Enable Output. The signal goes to High level when VGATE is lower than VGATE1

during turn-off.

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.
