Two n-channel MOSFET driver ICs can be used in rapid charging applications
Toshiba Electronics Europe has launched two n-channel MOSFET drivers suitable for rapid-charging and other high current applications.
The TCK401G (active-high) and TCK402G (active-low) charge pump driver ICs are suitable for high current mobile charging applications when used in conjunction with low RDS(on) n-channel MOSFETs, says Toshiba. The driver ICs support several built-in safety functions, including over-voltage protection, inrush current reduction and auto output discharge.
Operating from an.7 to 28V DC input voltage, the devices draw just 121-microA of quiescent current (IQ). Switching times for the gate voltage are 0.58-milli seconds (on) and 16.6-micro seconds (off).
A high-efficiency power supply circuit can be realised by using one of the new drivers with one or two external n-channel MOSFETs that have a maximum voltage rating and suitable on-resistance, explains Toshiba. An example is the combination of a TCK40xG driver IC and the low on-resistance SSM6K513NU MOSFET can be used to build a 100W power supply for mobile or consumer applications, with a very compact footprint, says the company.
The integrated driver ICs are housed in the small WCSP6E package, which measures 0.8 x 1.2 x 0.55mm.
Volume shipment of the TCK401G and TCK402G MOSFET driver ICs has started.
