Overvoltage Protector handles USB charging applications.

March 26, 2008 - Designed for portable and consumer devices such as cell phones, MP3 players, set top boxes, and computers, Model NCP361 consumes 20 µA, and features overcurrent protection at 750 mA typical. Offered in lead-free 2.0 x 2.0 mm DFN-6 package, it also offers protection of VBUS up to +20 V, and uses internal P-channel FET, eliminating need for external device. Negative-going flag (FLAG) output alerts about faults, while enable pin allows device to be forced to off-state.

ON Semiconductor Introduces Integrated Overvoltage Protection Controller Dedicated to USB Charging Protection in Portable and Consumer Devices

The NCP361 delivers superior performance, reduces system cost and optimizes board space for cell phone, MP3 player, set top box, computer and other consumer applications

PHOENIX, Ariz. - Mar. 10, 2008 - ON Semiconductor (Nasdaq: ONNN), a global leader in efficient power semiconductor solutions, has introduced the NCP361- an integrated overvoltage protector dedicated to USB charging applications for portable and consumer devices, such as cell phones and MP3 players, set top boxes and computers.

The NCP361 uses an internal P-channel FET, making the need for an external device unnecessary and thus reducing the system cost and the Printed Circuit Board (PCB) area of the application board. If overvoltage from a wall adapter occurs, causing the input voltage to exceed the overvoltage threshold, the NCP361 instantaneously disconnects the output from the input to protect the downstream system for optimal protection. The NCP361 offers lower quiescent current than competitive ICs and very low current consumption at 20 microamps (uA).

For added protection, the NCP361 features overcurrent protection at 750 milliamps (mA) typical) It has a negative-going flag (FLAG) output which alerts the system that a fault has occurred. The enable pin allows this overvoltage protection (OVP) device to be forced to an off-state. It also offers protection of VBUS up to +20 V, a more precise voltage threshold than discrete zener-based devices.

"Portable devices are especially vulnerable to electrostatic discharge due to their USB and other ports," said Marie Therese Capron, director of ON Semiconductor's low voltage power management business unit. "This creates a challenge for designers to provide extra protection to very sensitive components on crowded boards. ON Semiconductor's solutions, including the NCP361, provide best-in-class integrated protection devices in tiny packages that are ideal for implementation in ever-shrinking portable handheld devices."

The NCP361 is offered in the lead-free very small 2.0 mm x 2.0 mm DFN-6 package. Budgetary pricing for the NCP361 is $0.40 USD per unit in quantities of 3,000.
