Micrel Creates 1-Square Millimeter Dual-Input, Push-Button-Reset IC With Extended Setup Delay Times for Generating Hard Resets
SAN JOSE, CA -- (MARKET WIRE) -- 03/26/12 -- Micrel, Inc. (NASDAQ: MCRL), an industry leader in analog, high-bandwidth communications and Ethernet IC solutions, today introduced the MIC2782, one of the world's smallest push-button-reset ICs in the industry. Delivered in 0.8mm x 1.2mm Chip Scale Packaging, the MIC2782 features dual push-button reset inputs and extended setup periods of 6 to 12s. Intended for safely generating hard system resets, the dual-inputs and long setup periods protect against accidental system resets in Smart Phones, tablets, eBooks, set top boxes, personal navigation devices and toys. The MIC2782 is currently available in volume quantities, with 1,000 quantity pricing starting at $0.25. Samples can be ordered at: http://www.micrel.com/ProductList.do.
"The MIC2782 was designed expressly for consumer product manufacturers seeking to virtually eliminate the possibility of accidental hard resets," stated Brian Hedayati, marketing vice president for the Analog business unit at Micrel (MCRL). "The dual-input MIC2782 offers an elegant, flexible solution in less than 1 square millimeter while limiting the supply current to 2.2mA. This makes the device eminently suitable for space-constrained, power-sensitive applications such as Smart Phones and tablets."
The MIC2782 generates a reset pulse for a reset timeout period of 0.5s, 1s or 2s, after both push-button inputs have been held low for a selectable setup period of 6s, 8s, 10s, or 12s. The device also features a second output that immediately asserts if both push-button inputs have been asserted, and deactivates if one or both inputs are released. The MIC2782 provides 65kOhm pull-up resistors on the push-button inputs. Designers can tie both push-button inputs together if they desire a single push-button input. Outputs are open-drain and can sink 0.5mA of current from a 1.5V supply. The MIC2782 operates over the 1.5V to 5.5V supply voltage range, consuming just 2.2mA of supply current at 3.3V. It is available in a space saving, 6-bump, 0.4mm pitch, 0.8mm x 1.2mm x 0.525mm Wafer Level Chip Scale Package, and operates over the -40degC to +85degC temperature range.
