Application Field:

The AP2401B34DNTR-G1 is an ideal power switch for automotive, industrial and consumer applications where load current handling, load isolation and power distribution are needed. It is widely used in automotive systems including navigation systems, security systems, infotainment and comfort systems, and climate control systems. This IC is also suitable for high power systems, such as battery management systems, active cellphone modems, and PLC industrial systems. In addition, this power switch is also an ideal choice for consumer device designs such as battery powered toys, digital cameras, and other low power appliances.

Working Principle:

The AP2401B34DNTR-G1 is a wide voltage range load switch that utilizes hysteretic control. When the load switch is enabled, the applied current is compared with the load switch’s setpoint. If the setpoint is exceeded, the load switch will close with the current regulated to its setpoint. The load switch will then remain closed until the current drops below a lower setpoint, at which point the switch will open. This allows for improved regulation, over traditional switch operation, by maintaining accuracy even when there is a varying input voltage. The IC also includes overvoltage and reverse polarity protection, to protect the switch from damage.

The AP2401B34DNTR-G1 is protected by a fault current limiter and active shoot-through protection. The fault current limiter will limit the output current to a safe levels, while the active shoot-through protection prevents current from flowing in parallel paths which can cause damage to the switch. In addition, the IC includes thermal shutdown protection which prevents damage due to overheating.

The AP2401B34DNTR-G1 is designed for low power operation and is capable of switching both high and low current requirements. The operating voltage range is from 1.0V to 10V, with a maximum open circuit current at 30 mA. A low-power operating mode is also available, which can significantly reduce power consumption at high switching frequencies. The AP2401B34DNTR-G1 is also optimized for excellent EMC tolerances, making it suitable for a wide range of applications.

The AP2401B34DNTR-G1 is a versatile and highly efficient power switch that is suitable for use in a wide variety of applications. It is easy to use and provides fault current limiting, active shoot-through protection, and improved regulation over traditional switch operation. This power switch also includes thermal shutdown protection and is optimized for excellent EMC tolerances. The AP2401B34DNTR-G1 is a reliable, low-power consumption solution suitable for automotive, industrial, and consumer applications.
