LM219DT is a low voltage, low power, single supply, dual-hysteresis comparator with an internal protection circuit. It is a member of a family of high performance comparators designed for single supply operation. The comparison accuracies and tolerance ranges of the LM219DT make it an ideal choice for applications requiring analog voltage comparison and signal detection. The LM219DT is capable of operating over a wide supply voltage range of 2.7-36V, and it includes an open-drain output that can be used to drive higher power loads.
The LM219DT is available in a plastic SOT-23 surface-mount package and is manufactured using an advanced CMOS process. The LM219DT features an integrated E=C protection circuit, providing protection against overvoltage, under-voltage, over-current, and short-circuit conditions. A unique feature of the LM219DT is its high accuracy and temperature compensation, which enable it to maintain near-accurate comparison accuracies over a wide range of temperatures.Application Field
The LM219DT can be used in applications such as security systems, motor speed control, and counter circuits. It can also be used in motion detection and detection of acceleration, deceleration, and vibration. Due to its low power consumption, the LM219DT is ideal for battery-operated applications such as wireless sensor modules and medical devices.
The LM219DT is well-suited for automotive applications, due to its robust protection circuitry and wide supply voltage range. It is ideal for applications such as engine speed control, tire pressure monitoring systems, and automotive infotainment systems. Working Principle
The LM219DT is based on a differential amplifier circuit, which compares two voltage inputs to determine their relative levels. The first input, referred to as the + input or non-inverting input, is connected to the positive supply while the second input, referred to as the - input or inverting input, is connected to the negative supply. The LM219DT features an output stage that switches between a logic high and logic low state, depending on the difference between the two inputs. The LM219DT has two hysteresis levels that can be selected. The first hysteresis level is greater than the second hysteresis level, and the hysteresis level selection is controlled by a pin in the LM219DT package. When the input voltage crosses the first hysteresis level from below, the output of the LM219DT will switch from a logic low to a logic high state. When the input voltage crosses the second hysteresis level from above, the output will switch from a logic high to a logic low state. The LM219DT features an open-drain output that can be used to drive higher power loads. The output can drive up to 500mA with a maximum peak current of 1A and a maximum output voltage of 36V. The LM219DT is also capable of operating over a wide temperature range, from -55°C to +125°C.In conclusion, the LM219DT is a low voltage, low power, single supply, dual-hysteresis comparator with an internal protection circuit. Its features make it an ideal choice for applications requiring analog voltage comparison and signal detection in fields such as security systems, motor speed control, counter circuits, motion detection and automotive applications.
