Description : Microprocessor Supervisory Circuits in 3-Lead SC70 and SOT-23

The ADM803/ADM809/ADM810 supervisory circuits monitor the power supply voltage in microprocessor systems. They provide a reset output during power-up, power-down, and brownout conditions. On power-up, an internal timer holds reset asserted for 240 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 ADM803 and ADM809 provide an active low reset signal (RESET), while the ADM810 provides an active high signal (RESET) output. The ADM809 and ADM810 have push-pull outputs whereas the ADM803 has an open-drain output, which requires an external pull-up resistor.

Description : Microprocessor Reset Circuits

The ADM181x range of voltage monitoring circuits can be used in any application where an electronic system needs to be reset when a voltage increases above or below a predetermined value.
Because of the “reset delay time” incorporated into the ADM181x series, these devices can provide a safe startup for electronic systems. Before a system initializes, the power supply must stabilize. Using the ADM181x series ensures that there are typically 150 ms for the power supply to stabilize before the system is reset and safe system initialization begins.
The ADM181x series of microprocessor reset circuits are available in low cost, space-saving SOT-23 packages.

Description : 15 kV ESD Protected, 2.7 V to 3.6 V Serial Port Transceivers with Green Idle

The ADM3311E is a three driver/five receiver product designed to fully meet the EIA-232 standard while operating with a single +2.7 V to +3.6 V power supply. The device features an on-board, charge pump, dc-to-dc converter, eliminating the need for Dual power supplies. This dc-to-dc converter contains a voltage tripler and voltage inverter, which internally generates positive and negative supplies from the input +3 V power supply. The dc-to-dc converter operates in Green Idle Mode, whereby the charge pump oscillator is gated on and off to maintain the output voltage at ±7.25 V under varying load conditions. This minimizes the power consumption and makes these products ideal for battery powered portable devices.
