The LM2903ATH-13 IC is a single-supply, low-power, low-voltage comparator designed for power management applications. It features an open-drain output, which makes it suitable for use in applications that require this type of output. It has a wide operating range, from 4.5V to 36V, making it well suited for use in 5V logic systems. It is designed to be compatible with 3.3V, 5V and 3.5V logic systems. It has an operating temperature range of 0°C to +70°C, making it suitable for use in most applications.
The IC consists of two differential amplifiers inside. The first amplifier is the voltage-to-current stage and the second is the current-to-voltage stage. The voltage-to-current stage converts the input voltage to a current and is used as a reference current for the second stage. The second stage is the current-to-voltage stage and it converts the current from the voltage-to-current stage to an output voltage. The output voltage is then compared to the reference voltage. If the output voltage is equal to or less than the reference voltage, then the comparator will output a logic high voltage. If the output voltage is greater than the reference voltage, then the output will be a logic low voltage.
The LM2903ATH-13 is designed for fast switching applications, such as over-voltage/over-current protection, regulated power supplies and voltage references. The comparator has a low offset voltage, which ensures reliable operation with minimal drift over time and temperature. It also has fast propagation delays and wide slot detection angles, which makes it well suited for use in motor drives and AC motor control systems. The open-drain output is also useful for interfacing with P-channel MOSFETs, enabling the design of power-saving systems.
In addition to its intrinsic circuitry, the LM2903ATH-13 also has an independent reset feature. This feature is useful for ensuring that the comparator does not remain active when the input is removed and a reset of the circuitry is essential. The reset can be triggered either internally or externally, providing flexibility in the design of the system.
The LM2903ATH-13 has a wide range of applications, including power supply monitoring, over-voltage/over-current protection, voltage references, motor drives and AC motor control systems. It is suitable for use with both 5V and 3.3V logic systems, and with its fast propagation delays and low offset voltage it is particularly well suited for use in high speed logic systems.
The LM2903ATH-13 is a robust, low-power comparator designed for use in power management applications. With its wide operating range, fast switching speed and independent reset feature, it is an ideal choice for use in applications where reliability, flexibility and accuracy are of paramount importance.
