 Description

The DIA74H120 is a fully protected, quad-channel,

smart, high-side driver and housed in EP-TSSOP28

package. Every channel integrates a 120 mΩ

high-voltage NMOS power FET to drive the

automotive grounded loads.

The DIA74H120 offers complete protection functions.

The device enables to adjust internal current limit by

using external resistors, which can limit the inrush or

overload current. With the current limit function, its

internally integrated comprehensive overtemperature

protection scheme can greatly improve the reliability

of the system.

High-accuracy current sense enables to monitor the

current flowing through the switch in real time so as to

provide a more accurate diagnosis without further

external calibration.
