The TS862AIPT is a linear-comparator circuit with an open-collector output stage. It is used to compare two voltages and drive an output to indicate when one voltage is greater than the other. This makes it ideal for detecting and actuating upon a range of voltage-based preconditioned signals. The TS862AIPT comes in a SOIC-8 package and has a wide operating voltage range from 2.7 V to 5.5 V.

The circuit of the TS862AIPT can be divided into two distinct sub-circuits: a Signal Input Comparator and an Output Stage. The Signal Input Comparator compares two input signals and produces a logical 1 or 0 at its output. The comparison happens when one of the inputs, named VIN+, exceeds the voltage present at the other input, named VIN-.

The output stage of the TS862AIPT drives an open-collector transistor to operate with maximum flexibility and low power; it provides is a low resistance with a high current driving capability. Also, the inverted output option allows a way to invert the logic of the output signal before it is transmitted downstream. This is useful in applications where the circuitry downstream the TS862AIPT requires a logic reversal of the output.

The TS862AIPT is typically used to detect over- and undervoltage conditions due to transient fluctuations in the power supply or sudden changes in load current. In order to achieve this task, the user needs to set the voltage differential, typically done by a trimmer, between the two input signals. The output will then be driven high applicable when the VIN+ exceeds the voltage at VIN-, and vice versa. The TS862AIPT can also be used to overvoltage protection circuits when connected to a suitable driver circuit that can turn on or off the remote circuit.

The TS862AIPT’s on-chip protection features include under-voltage lockout, overtemperature protection and short-circuit protection. Furthermore, it contains an active-high enable pin which allows the user to disable the TS862AIPT before LV switch-on and reset the circuit after large overloads, allowing it to be operated with external active components.

The combine of the linear comparator with the open-collector output stage makes the TS862AIPT an ideal choice for voltage-based applications where an output drive is required. Its wide range of operating voltages, low current consumption and its protection features make it suitable for a variety of applications. From overvoltage protection circuits to temperature monitoring and switching, the TS862AIPT can be an excellent choice.
