PIN FUNCTIONS

N.

Name

Function

1

OUT1

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

Positive Supply Voltage (referred to COM).

See under voltage lockout functioning

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

4

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).

5

INV-OUT

Inverted Output Driver Status.

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

6

ALARM

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

7

MON_DELAY

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

9

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)

10

DELAY

11

SELECT

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

transformer mode.

12

ON_LEV_PROG

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

13

ON_SENSE

On State Monitor.

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

14

Negative supply voltage (referred to the COM).

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

15

COM

Ground

16

OUT2

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