Infineon Extends Operating Frequency of Intelligent Power Switches to Match Standard MOSFET Switching Performance
SAN JOSE, Calif.--Aug. 3, 1999--Introduction of Speed TEMPFET(R) (Temperature-Protected FETs) Intelligent Power Switches Opens Door to New Automotive and Industrial
Applications
Infineon(TM) Technologies Corporation, formerly Siemens Microelectronics, Inc., today announced a trio of high-speed additions to its family of single-channel, low-side TEMPFET intelligent power switches with protection against over-temperature.
By operating across the same frequency range as standard power MOSFETs and well beyond the capabilities of other power-protected switches, Infineon's new power switches, designated Speed TEMPFET switches, extend the advantages of temperature protection to applications requiring higher frequency switching. Infineon's use of chip-on-chip technology enables an isolated temperature sensor to be combined with a standard power MOSFET. Like other members of the TEMPFET intelligent power switch line, the new BTS 244Z, BTS 247Z and BTS 282Z Speed TEMPFET switches also provide overload protection.
"The transition from standard MOSFETs to protected switches has been restricted by the inherent frequency limitations of intelligent power switches," noted Shawn Fogarty, Infineon's product marketing manager. "With Speed TEMPFET switches, Infineon broke the switching frequency barrier, and in the process, paved the way for the introduction of intelligent control of power switches to a wide range of new applications."
With rise and fall times ranging from just 30 to 55 nanoseconds, the new Speed TEMPFET switches are ideal for medium to high-frequency PWM (Pulse Width Modulation) applications such as automotive lighting, climate control, electric power steering, fan control and wiper drivers. Industrial applications include relay and fuse replacement, power control in appliances and portable tools, various automated designs in robotics, and industrial automation.
Infineon's Speed TEMPFET switches also open the door for temperature-protected switching to new applications demanding higher load currents. The BTS 282Z is rated at a new high of 51 Amps of load current with 10.0V gate source voltage and less than 0.5V drain source. Under similar operating conditions, the BTS247Z and 244Z are rated at 19 and 26 Amps of load current, respectively.
In quantities of 10K, prices for the new intelligent power switches start at $1.64 for the BTS 247Z, $1.95 for the BTS244Z and $2.74 for the BTS 282Z. All three devices are available in the TO-220 package. The BTS 244Z and BTS247Z are housed in 5 pin TO-220 packages while the BTS 282Z is offered in a 7-pin TO-220 design. The products are currently being sampled and volume production is available.
