Nexperia has expanded its analog and logic product portfolio with the introduction of a new load switch family. The new line includes the NPS4053, an integrated 5-V load switch, which is designed with a small footprint and increased system protection.
“Load switches are essential components in the operation of a wide array of modern electronic systems,” said Nexperia. “They play a crucial role in managing current/voltage in a controlled manner from source to the load.”
Nexperia said the NPS4053 is positioned closest to the load, in a typical power chain, for power sequencing and inrush-current control and shutting off power islands to conserve power. This is a benefit in battery-operated equipment.

In addition, the load switch simplifies circuit design and has an 85% smaller PCB footprint than a comparable network of discrete components, according to the company. This makes them suited for portable devices such as notebook computers, docking stations, desktops and automotive infotainment systems.
The NPS4053 operates with an input voltage of 2.5 V-5.5 V and contains a 55-mΩ self-protected MOSFET, which manages the flow of power to the load. A key feature is the programmable current-limiting circuitry, which enables precise control of the load current over a range of 110 mA to 2.5 A with an accuracy of +6%. Other features include support for “true” reverse current blocking for end-to-end system protection and an integrated fault indicator pin that alerts the host controller of a fault event.
The NPS4053 is UL 62368 recognized and an automotive AEC-Q100 qualified version is also available. The device is offered in both leaded and leadless (HWSON 6) packages.
