TelCom Semiconductor Announces New TC6501 and TC6502 Thermal Management Devices

January 09, 2000 by Jeff Shepard

TelCom Semiconductor Inc. (Mountain View, CA) recently announced the latest additions to its thermal management family of products, the TC6501 and TC6502. The devices are low-power temperature switches with pin-selectable hysteresis in five-pin SOT-23A packages.

According to TelCom, the switches require no external components and are designed for applications where small size, low power and low installed cost are critical. The TC6501 and TC6502 are designed to be suitable for applications ranging from notebook computers and PCs to set-top boxes. The TC6501 and TC6502 are designed for hot-temperature monitoring.

According to the company, the devices assert a logic signal when the die temperature crosses the factory-programmed thresholds, available from +35 degrees C to +115 degrees C in 10C increments. The devices are designed to dissipate very little power with a low 17uA supply current and operate over the entire -55 degree C to +125 degree C temperature range while offering +/-0.5C (typical) accuracy.

The TC6501 is designed to offer an open drain, active-low output meant for microprocessor reset control. The TC6502 has a CMOS, active-high output designed to drive a logic level MOSFET to turn on a fan element.

"TelCom continues to expand its thermal-management product line with the addition of the TC6501 and TC6502 temperature sensors," said Mark Shepherd, product marketing manager at TelCom. "These tiny switches draw roughly half the current of their closest competitor, making them the ideal choice for power-critical applications."

The TC6501 and TC6502 are available in five-pin SOT-23A packages. In quantities of 10,000, pricing for both devices starts at $0.58 each.
