Nexperia adds first integrated 5V load switch
Provides smaller footprint and superior system protection
Nexperia has released the NPS4053, a load switch designed to provide a smaller footprint and to help increase system reliability and ensure safety. The device is optimised for applications in portable devices such as notebook computers, desktops, docking stations, and automotive infotainment systems.
In a typical power chain, the NPS4053 is commonly positioned closest to the load for power sequencing and inrush-current control, and shutting off power islands to conserve power, making it especially valuable in battery-operated equipment. This monolithic solution simplifies circuit design and has an 85 percent smaller PCB footprint than a comparable network of discrete components, according to Nexperia.
The NPS4053 operates with an input voltage of 2.5 V-5.5 V and contains a 55 mΩ self-protected MOSFET, which efficiently manages the flow of power to the load. This device includes programmable current-limiting circuitry allowing precise control of the load current over a range of 110 mA to 2.5 A with an accuracy of +6 percent. The device also supports 'true; reverse current blocking, providing robust end-to-end system protection. To further enhance system monitoring, the NPS4053 integrates a fault indicator pin that alerts the host controller of a fault event.
Among other certifications, the NPS4053 is UL 62368 recognised and an automotive AEC-Q100 qualified version is also available. For flexibility, the device is offered in both leaded and leadless (HWSON 6) packages.
