Definition

1

CSNS

Output Current Monitoring

This terminal is used to output a current proportional to the high-side OUT current and

is used externally to generate a ground-referenced voltage for the microcontroller

(MCU) to monitor OUT current.

2

TEMP

Temperature Feedback

This terminal reports an analog value proportional to the temperature of the GND flag

(terminal 13). It is used by the MCU to monitor board temperature.

3

EN

Enable

(Active High)

This is an input used to place the device in a low current sleep mode. This terminal has

an passive internal pulldown.

4

INHS

Serial Input High Side

The input terminal is used to directly control the OUT. This input has an active internal

pulldown current source and requires CMOS logic levels.

5

FS

Fault Status

(Active Low)

This is an open drain-configured output requiring an external pull-up resistor to

is active LOW.

6

INLS

Serial Input Low Side

The input terminal is used to directly control an external low-side N-channel MOSFET

and has an active internal pulldown current source and requires CMOS logic levels. It

can be controlled independently of the INHS depending of CONF terminal.

7

CONF

Configuration Input

This input terminal is used to manage the cross-conduction between the internal high-

side N-channel MOSFET and the external low-side N-channel MOSFET. The terminal

has an active internal pullup current source. When CONF is at 0 V, the two MOSFETs

are controlled independently. When CONF is at 5.0 V, the two MOSFETs cannot be on

at the same time.

8

OCLS

Low-Side Overload

terminal has an active internal pullup current source. It must be connected to an

external resistor.

9

DLS

Drain Low Side

This terminal is the drain of the external low-side N-channel MOSFET. Its monitoring

allows for protection features.

10

GLS

Low-Side Gate

This terminal is an output used to drive the gate of the external low-side N-channel

MOSFET.

11

SR

Slew Rate Control

A capacitor connected between this terminal and the ground is used to control the

output slew rate.
