The DS1812-10 is a supervisory circuit best suited for microprocessor-based systems. It is specifically designed to monitor microprocessor operations and signals during power-up, power-down and normal operation. It integrates many important functions,such as reset, power-on reset, under-voltage reset and delay reset, into a single chip. The DS1812-10 monitors system voltages and automatically resets the microprocessor when power is applied. It also ensures that the microprocessor will not be reset prematurely due to transient pulses during power-on.
In addition, it allows the user to properly time the sequence of power-on events, such as powering up memory and peripherals. This is accomplished by providing two programmable reset outputs. The DS1812-10 can be used in any application that requires reliable system startup and precision voltage monitoring. It is available in a wide variety of package sizes and has an operating temperature range of 0 to +70 °C.
The DS1812-10 is divided into four distinct areas: Input, Control, Supervisor and Output. The Input section accepts an analog input voltage measurement and converts it to a digital value. This digital value is then compared to the programmed voltage thresholds. The Control section controls the reset output logic based on the comparator result. If a valid reset signal is indicated, the reset line will be asserted. If no valid reset signal is indicated, the reset line will be deasserted. The Supervisor section contains the power-up, power-down and power-hold circuitry, as well as the Latch-Up protection diode. The Output section drives the reset output to the microprocessor.
The DS1812-10 uses two primary operating modes: Hold-Mode and Reset-Mode. In Hold-Mode, the power-hold circuitry ensures that the microprocessor won′t reset during power-on transients. The power-hold circuitry also prevents the microprocessor from resetting due to minor deviations from the programmed voltage thresholds. In Reset-Mode, the reset output is asserted if the voltage measurement is lower than the programmed threshold. It is deasserted when the voltage measurement returns to the valid operating range.
In summary, the DS1812-10 is a supervisory circuit best suited for microprocessor-based systems. It integrates important functions, such as reset, power-on reset, under-voltage reset and delay reset, into a single chip.
