PIN FUNCTIONS

Name

Function

OUT1

Output of high side driver (emitter of power NPN transistor).

2VCC

Positive Supply Voltage (referred to COM).

See under voltage lockout functioning

3VPOS

Positive Bias Voltage (collector of the NPN power transistor).

CLAMP_PROG

First Step of the Gate Voltage Programming.

The programming is achieved setting an appropriate voltage on this pin (i.e. using a resistence

voltage divider).

INV-OUT

Inverted Output Driver Status.

The buffer output is able to drive some auxiliary circuit (i.e. a LED).

ALARM

Diagnostic Output Signal. A fault condition is signalled by this output buffer.

MON_DELAY

VON Monitor Delay. An R-C network connected between this, the COM and the VREF pins,

define tMON_DELAY time interval (see fig 4)

8VREF

Output of the 5V/10mA internal voltage reference.

INPUT

Input signal.

The driving signal can be a logic level either active LOW (inverted mode) or HIGH (direct

mode) in the Logic Level or a pulse in the Pulse Transformer Mode (see Figure 2)

DELAY

On Triggering Delay. An R-C network connected between this, the COM and the VREF pins,

definethe tDELAY time interval (see fig 4)

SELECT

Select the direct/inverted mode in the Logic Level Mode. It’s also the reference pin in Pulse

transformer mode.

ON_LEV_PROG

VON level programming.

This pin is used to set the VON monitor level. The programming is achieved setting an

appropriate voltage on this pin (i.e. using a resistive divider).

ON_SENSE

On State Monitor.

This pin is used to monitor the turning on of the external power device.

VSS

Negative supply voltage (referred to the COM).

This pin is the source of the low side driver DMOS.

COM

Ground

OUT2

Output of the low side driver (drain of the DMOS).
