The ADM6326/ADM6328/ADM6346/ADM6348 devices provide low cost solutions for protecting sensitive circuitry, such as micro-processor and telecommunications circuitry.
With built-in glitch immunity, ultralow supply currents, and 24 reset threshold voltage options, the ADM6326/ADM6328/ADM6346/ADM6348 not only ensure that systems are immune to fast transients on VCC, but also that the devices are suitable for monitoring a variety of supply voltages in low power, portable equipment.
These devices provide a reset output during power-up, power-down, and brownout conditions. On power-up, an internal timer holds RESET asserted for at least 100 ms. This holds the microprocessor in a reset state until conditions have stabilized. The reset output remains operational with VCC as low as 1 V.
The ADM6326 and ADM6346 have an active low push-pull reset output. The ADM6328 and ADM6348 have an active low open-drain reset output, which requires an external pull-up resistor. The ADM6326 and ADM6328 offer a choice of ten reset thresholds in increments between 2.2 V and 3.08 V, whereas the ADM6346 and ADM6348 offer a choice of 14 reset thresholds between 3.3 V and 4.63 V. Not all options are released for sale as standard models. See the Ordering Guide for details.
These devices are available in a 3-lead SOT-23 package and operate over the extended temperature range of −40°C to +85°C.
