NCV8405STT3G is a Power Management Integrated Circuit (PMIC) used for power distribution and load drive. This device incorporates three independent power switches, a low-side load drive circuit and a low dropout linear regulator. It provides an efficient combination of features for DC/DC and other power distribution control.

The NCV8405STT3G is designed specifically to control the output power of a low-power DC/DC system. This PMIC can be used to control a wide range of DC/DC systems, including buck, boost and buck/boost converters. Its selectable current limit, dynamic on/off control, and overcurrent protection make it ideal for many switching power supply designs. The NCV8405STT3G also incorporates a current-mode, PWM-controlled linear regulator with low dropout voltage and low noise operation.

The NCV8405STT3G has three independent power switches, each with individual current limiting and on/off control. The switches are capable of switching loads up to 6 A, and each have an adjustable overcurrent threshold protecting the device from dangerous over-current conditions. The switches also include a selectable dead-time to limit switching transients. The integrated low-side load drive supports an output current of up to 2.5 A, with complementary switching signals for each power switch.

The NCV8405STT3G includes a low dropout linear regulator, which can provide up to 3 A of output current for moderate power requirements. The regulator includes adjustable overcurrent protection and under-voltage lockout, as well as an enable pin to control the power switch. The regulator also includes current-mode, PWM-controlled feedback, which allows the output voltage to adjust with line and load changes.

The NCV8405STT3G also includes an enable pin with built-in digital logic and open-drain circuitry. This enable pin can be used to control the output enablement of all three power switches. Two analog monitor input pins are also included, which allow the system to monitor the load current and output voltage.

The NCV8405STT3G has a wide range of applications, including industrial motor control, HVAC systems, small appliance control, lighting control, security systems, and server applications. This device can be used to efficiently control the output of low-power DC/DC systems in any of these applications. With its overcurrent protection and enable pin, the NCV8405STT3G provides additional safety and flexibility for these demanding systems.
