Power Distribution Switches, Load Drivers
ITS4142NHUMA1 is a multifunctional power distribution switch integrated in an SOT-23 package. It is designed to reduce printed circuit board space and keep costs to a minimum.
The device can be used in multiple switching applications, such as between the power supply and a load, or between two power supplies. With its low current consumption, ITS4142NHUMA1 can also simplifiy design by controlling multiple outputs or channels with one pin.
Application
ITS4142NHUMA1 is suitable for automotive, industrial and mobile phone applications. It is particularly well suited to applications where the control voltage is low. By combining multiple channels, ITS4142NHUMA1 can control several outputs at once with only one pin.
Its small size and high efficiency make it extremely attractive for use in portable devices. It is capable of supporting a wide input voltage range and high operating temperature and has been tested to comply with AEC-Q100, making it suitable for automobile applications.
Working Principle
The device\'s internal circuitry is composed of a series of transistors, diodes and resistors. Its main function is that it can switch between two power sources. Its power consumption is low, thus preserving the battery charge. The ITS4142NHUMA1 works in the following manner:
The supply voltage is provided to the VIN pin which is connected to an internal non-over-current regulation switch. The switch connects the VIN pin to either the VOUT1 or VOUT2 pins depending on the logic level at the CTRL pin. When CTRL pin is pulled high the switch is opened, when the CTRL pin is pulled low the switch is closed. By alternating between the two logic levels, the device can switch between two power sources.
Finally, the device is also equipped with a slew-rate circuit, a UVLO (Under Voltage Lock Out) circuit, as well as Thermal Shutdown protection. The slew-rate circuit limits the rate of rise and fall of the output current, reducing switching losses. The UVLO circuit prevents uncontrolled current flow during undervoltage conditions of the supply voltage. The thermal shutdown circuit prevents excessive temperature due to thermal runaway.
Conclusion
The ITS4142NHUMA1 is a multifunctional power distribution switch in an SOT-23 package. It can be used in multiple switching applications and its small size and low current consumption make it well suited for portable applications. The device offers a series of protective functions, such as the slew-rate, UVLO and Thermal Shutdown, for a reliable and safe operation.
