Working Principles

The LTC2900-2CMS#TRPBF operates by continuously monitoring the voltage level at the TH pin. When the voltage falls below the threshold set by an external resistor divider connected to the TH pin, the RESET output is asserted, indicating a low voltage condition. The reset timeout can be adjusted using an external capacitor connected to the MR pin. The device also features a power-on reset circuit that ensures a proper system initialization upon power-up.
