ON unveils overvoltage protection circuit
An ON Semiconductor product story
Edited by the Electronicstalk editorial team Nov 24, 2008
ON Semiconductor has introduced the NUS6189 overvoltage protection circuit, to protect sensitive electronic circuitry from overvoltage transients and power supply faults.
It is a device that integrates the performance and functions of an overvoltage protection (OVP) circuit, a 30V P-channel power Mosfet, a low VCE(sat) transistor and a low Rds(on) power Mosfet into a space-saving 3mm x 4mm x 0.9mm package.
It is optimised for applications that use an external AC-DC adapter or car accessory charger, such as mobile phones, PMPs and mobile internet devices.
By integrating the four separate device functions commonly needed for protection within portable devices into a single IC, the NUS6189 reduces the PCB space required by up to 40 per cent.
In addition, the device's integrated design delivers very low power dissipation, significantly reducing heat and improving battery life.
Designed to handle large inrush peak currents, the NUS6189 is a suitable complement to power management ICs offered by ON Semiconductor, and to CDMA chipsets - both being designed into portable devices.
With an overvoltage turn-off time of less than 1 microsecond, the device quickly disconnects the input supply from the load during faults, assuring superior protection.
