The ADM8616/ADM8617 are supervisory circuits that monitorpower supply voltage levels and code execution integrity in micro-processor-based systems. A power-on reset signal generates whenthe supply voltage rises to a preset threshold level. The ADM8616/ADM8617 have an on-chip watchdog timer that can reset themicroprocessor if it fails to strobe within a preset timeoutperiod.Each part is available in the following nine reset thresholdoptions: 1.58 V, 1.67 V, 2.19 V, 2.32 V, 2.63 V, 2.93 V, 3.08 V, 4.38 V, and 4.63 V. There are four reset timeout options: 1 ms,20 ms, 140 ms, and 1120 ms. There are also three possible watchdog timeouts available: 6.3 ms, 102 ms, and 1.6 sec. Notall device options are released for sale as standard models. Seethe Ordering Guide for details.The parts differ in terms of reset output configuration. TheADM8616 is active-low with a push-pull output, while theADM8617 is active-low with an open-drain output.The ADM8616/ADM8617 are available in 4-lead SC70 packagesand typically consume only 5 μA, making them suitable for usein low power, portable applications.Applications Microprocessor systems Computers Controllers Intelligent instruments Portable equipment

Demonstration circuit DC1129A is a synchronous step down converter featuring the LTC3610, the high efficiency, high density DC/DC regulator. The input voltage range is from 4.5V to 24V. The output voltage is jumper-selectable and provides 1.2V, 1.5V, 1.8V or 2.5V at 12A load current. The regulator includes the controller and power MOSFETs in the 9mm by 9 mm QFN package.

The REF01 / REF02 / REF03 series of precision voltage references provide a stable 10.0 V, 5.0 V, or 2.5 V output with minimal change in response to variations in supply voltage, ambient temperature or load conditions. The devices are available in 8-lead SOIC, PDIP, CERDIP, and TO-99 packages, as well as 20-terminal LCC packages (883 only), furthering the usability of the devices in both standard and high stress applications.With an external buffer and a simple resistor network, the TEMP terminal can be used for temperature sensing and approximation. A TRIM terminal is also provided on the device for fine adjustment of the output voltage.The small footprint, wide supply range, and application versatility make the REF0x series of references ideal for general-purpose and space-constrained applications.Newer designs should use the ADR01 / ADR02 / ADR03 / ADR06 series of references, which offer higher accuracy and temperature stability over a wider operating temperature range, while maintaining full pin-for-pin compatibility with the REF01 / REF02 / REF03 series.
