Sprinter button on / off controller with debounce and power-start

Linear Technology Corporation (Linear Technology) introduced a button on / off controller - LTC2950, for DC / DC converters, processor interrupt logic and LT1111IS8 datasheet and adjustable on / off timer to provide start control. The device solves all the mechanical contact with the rebound on the inherent problems, while after the power is fully powered, you can also activate the power converter and LT1111IS8 price and the release of the processor. Power outage, LTC2950 interrupts the system processor to alert the processor to perform the necessary power and LT1111IS8 suppliers and housekeeping tasks; system to complete the disconnect operation, the LTC2950 can be ordered immediate ban on supply.

LTC2950 2.7V to 26V in a wide input voltage range, can take into account a variety of input power. 6μA supply current makes the IC suitable for battery-powered applications. To start signal both positive and negative polarity, Linear Technology now offers two versions of the LTC2950. Button input pin solid work environment designed specifically for noise, and can withstand up to ± 10kV of ESD impact.

LTC2950 8-lead 2 × 3mm DFN package, the help of portable instruments and handheld products to save design time and board space. It can work in commercial and industrial temperature ranges are available from stock in 1,000-piece quantities starts at $ 1.75 per piece.
