Cost-effective reset control for consumer kit

The SMR100 is a long-duration reset controller for cost-effective use in high-volume consumer applications.

The SMR100 is a long-duration reset controller for cost-effective use in high-volume consumer applications.

The SMR100 has a user reset that is controlled by long hold-down of a pushbutton as typically specified for satellite TV set-top box applications.

The hold-down time is user programmable from 0.3 to 40s.

Long hold-down time is used to avoid inadvertent user resetting.

Other features include a bad-power warning signal that trips when Vcc drops to 3.1V, and a reset that trips if Vcc drops to 3.0V.

The SMR100 is well suited to a variety of applications in consumer and customer-premises equipment.

These include TV set-top boxes, home DSL routers, cable modems, video equipment, digital cameras and handheld computing devices.

To speed OEM design, Summit offers graphical user interface (GUI) software to very rapidly tailor the SMR100 to their individual needs.

Summit GUIs are currently is use by hundreds of designers worldwide to program virtually all of Summit's products.

Once a user completes design and prototyping, summit's GUI automatically generates a hex data file to be transmitted to Summit for review and approval.

Summit then assigns a unique customer identification code to the hex file and programs the customer's production devices prior to final electrical test operations.

This ensures that the device will operate properly in the end application.

An evaluation card containing the SMR100 reset controller, all required associated circuitry, and a PC connector for "plug and play" programming are available.

Available in volume quantities today, the SMR100 comes in a highly compact 6-bump 1 x 1.5mm ultra-CSP package priced at $0.40 in 25,000-off quantities.

It is also available in 8-lead SOICs for $0.50 in the same quantities.
