Supertex TC6215 N- and P-Channel Enhancement Mode MOSFET
The Supertex TC6215 N-channel and P-channel enhancement mode dual MOSFET combines an advanced vertical DMOS structure and a high-quality gate manufacturing process to provide both the power handling capabilities of bipolar transistors and the high input impedance and positive temperature coefficient inherent in MOS devices. The Supertex TC6215 consists of high voltage, low threshold N-channel and P-channel MOSFETs in an 8-lead SOIC (TG) package. Both MOSFETs included in the TC6215 have integrated back to back gate-source Zener diode clamps and guaranteed Rds(on) ratings down to 4.0V gate drive, allowing them to be driven directly with standard 5.0V CMOS logic. These Supertex devices are free from thermal runaway and thermally-induced secondary breakdown.
Supertex CL3xx LED Drivers
Supertex´s CL3xx family of LED drivers is designed to drive three strings of LEDs at a constant current of 20, 25 or 30mA. The devices contain separate enable pins for each channel to allow PWM dimming, three-step linear dimming, and individual disconnection of any faulty LED string. These drivers by Supertex provide over-temperature protection, 90V standoff voltage, and a fixed drive current with a ±6% tolerance over a Vout range of 4-15V. The product is ideal for applications in low cost LED backlighting, LCD panels, indicator lamps, decorative lights, and general lighting.
