Microchip Debuts New TCM809/810 and TCM811/812

Microchip Technology Inc. (Chandler, AZ) announced the latest addition to its power management family, the TCM809/810 and TCM811/812 system supervisors. The TCM809/810 devices, housed in the SC-70 package, occupy only two-thirds the space required by a standard SOT-23 package, suitable for applications such as laptops, PDAs, cellular phones and pagers. The TCM811/812 devices, housed in four-pin SOT-143 packages with a low supply current of 6uA, are suitable for battery-powered applications.

The TCM811/812 devices feature a manual reset that can override the reset monitor in critical situations, and provide accurate Vcc monitoring and reset timing during power-up, power-down and brown-out/sag conditions. The system supervisors, offered in a variety of reset threshold (1.75V to 4.63V) options, require no external components.

"The addition of these low-power supervisors enables Microchip to offer designers a complete supervisory system solution, including current industry-standard packages and voltage options for almost all external-voltage monitoring applications," said Sarika Chaudhry, product-marketing engineer for the analog and interface product division at Microchip.

The TCM809/810 devices are available in both three-pin SOT-23 and SC-70 packages. Pricing for the TCM809/810 devices, in 1,000-unit quantities, start at $0.37 each. The TCM811/812 devices are available in four-pin SOT-143 packages. Pricing for the TCM811/812 devices, in 1,000-unit quantities, start at $0.52 each.
