MAX792/LCSE is a versatile PMIC (power management integrated circuit) designed for voltage monitoring and reset control solutions. It provides an ultra-precise adjustable reset threshold and a variety of control logic to facilitate a wide range of applications in digital systems, microprocessor-based systems, or any circuit that requires logic-controlled reset generation. MAX792/LCSE is available in the n 8-pin SOIC package, making it ideal for space-constrained applications.

As part of its supervising family, the MAX792/LCSE provides robust features to protect sensitive circuit components from damage and to ensure system stability and reliable operation. It features a monitored voltage range of 1.8V to 5.5V. The threshold voltage (Vm) and the reset delay time (tDS) can be modified to suit diverse system designs. In addition, the MAX792/LCSE includes an adjustable control logic output to enable reset pulse generation or to enable additional logic functions in the system. The MAX792/LCSE is available in two versions: MAX792 or LCSE. The LCSE version offers an additional pin that can be used to enable a system reset in a lockout state.

Applications of the MAX792LCSE integrated circuit typically include systems that require reset protection, such as telecom and networking equipment, embedded control systems, computers, digital systems, and similar equipment. The reset capability can also be used in critical connections points, such as when connecting a power source to a critical board, in order to monitor and detect unwanted voltage spikes.

The working principle of the MAX792/LCSE is quite simple. It uses a comparator to compare the monitored voltage (Vmon) to the set threshold voltage (Vth). If the monitored voltage exceeds the threshold value, the reset pulse is generated with a pre-set delay time (tDR). The reset pulse can also be enabled by other logic control signals at one of the control logic input pins. Once the monitored voltage drops below the threshold value, the reset is removed.

The MAX792/LCSE offers a wide range of features for reset monitoring and reset control. Its adjustable threshold and delay times allow the user to customize its behavior to suit various design requirements. In addition, its adjustable control logic outputs enable it to be used to generate reset pulses or other logic functions in a system. The MAX792/LCSE is available in an 8-pin SOIC package, making it an ideal solution for space-constrained applications. In summary, the MAX792/LCSE is a versatile and robust power management integrated circuit suitable for a wide range of applications.
