Phoenix, Ariz.ON Semiconductor is calling the NCP370 the industry's first integrated bi-directional device, with ± overvoltage protection (OVP) for cell phones, MP3/4, PDAs and GPS systems, and overcurrent protection (OCP) for portable accessories such as FM transceiver, load speakers and flash modules.
The NCP370 is designed to improve the front end protection of the portable devices by providing positive protection up to +28 V and negative protection down to -28 V. It also provides OCP for the external accessories, which are connected on the bottom connector and supplied via a lithium-ion battery.
Integrated low on resistance (Ron) N-channel MOSFETs support the direct high charge current up to 1.3A. The NCP370 is available with several overvoltage thresholds to address the maximum rating of the downstream applications. Additionally, the device offers a second reverse mode, enabling the regulation of the reverse current coming from a portable device's battery to supply the external accessories such as an FM transceiver, audio functions or flash capabilities universally connected on the bottom connector of the portable devices.
The NCP370MUAITXG is now available in a 3 mm x 3 mm x 0.55 mm LLGA-12, lead-free (Pb-free), RoHS compliant package.
Pricing: $0.80 per unit in 3,000 unit quantities.
