The ADM8323/ADM8324 are supervisory circuits that monitor power supply voltage levels and code execution integrity in microprocessor-based systems. An on-chip watchdog timer checks for activity within a preset timeout window. A reset signal can also be asserted by an external push-button switch through a manual reset input. The RESET output is either push-pull (ADM8323) or open-drain (ADM8324).A watchdog failure results in a low output on the RESET pin. A failure can be triggered either by a fast watchdog error (watchdog pulses too close together) or by a slow watchdog error (no watchdog pulse within the timeout period). This effectively gives a window to observe the watchdog pulse. The watchdog timeout is measured from the last falling edge of the watchdog input (WDI). There are eight different watchdog windows available, as shown in Table 5.Each device is available in a choice of 26 reset threshold options from 2.5 V to 5 V in 100 mV increments. There are also four reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms (minimum). Not all device options are available as standard models. See the Ordering Guide for details.The ADM8323/ADM8324 are available in a 5-lead SOT-23 package and typically consume only 10 μA, making them suitable for use in low power portable applications.Applications Automotive Microprocessor systems Computers Controllers Intelligent instruments Portable equipment

The ADP2126 / ADP2127 are high frequency, step-down, dc-to-dc converters optimized for portable applications in which board area and battery life are critical constraints. The fixed 6 MHz operating frequency enables the use of tiny ceramic inductors and capacitors and the regulators use spread spectrum frequency modulation to reduce EMI. Additionally, synchronous rectification improves efficiency and results in fewer external components.At high load currents, the ADP2126 / ADP2127 use a voltage regulating pulse-width modulation (PWM) mode that maintains a constant frequency with excellent stability and transient response. Light load operation is determined by the state of the MODE pin. In forced PWM mode, the converter continues operating in PWM for light loads. Under light load conditions in auto mode, the ADP2126 / ADP2127 automatically enter a power-saving mode, which uses pulse frequency modulation (PFM) to reduce the effective switching frequency, thus ensuring the longest battery life in portable applications.The ADP2126 / ADP2127 are enabled by a 6 MHz to 27 MHz external clock signal applied to the EXTCLK pin. Certain models can also be enabled with a logic high signal. When the external clock is not switching and in a low logic state, the ADP2126 / ADP2127 stop regulating and shut down to draw less than 0.3 μA (typical) from the source.The ADP2126 / ADP2127 have an input voltage range of 2.1 V to 5.5 V, allowing the use of single Li+/Li polymer cell, three-cell alkaline, NiMH cell, and other standard power sources. The ADP2126 / ADP2127 are internally compensated to minimize external components and can source up to 500 mA. Other key features, such as cycle-by-cycle peak current limit, soft start, undervoltage lockout (UVLO), output-to-ground short-circuit protection, and thermal shutdown provide protection for internal and external circuit components.APPLICATIONS Mobile phones Digital still/video cameras Digital audio Portable equipment Camera modules Image stabilization systems
