TSM1121IN PMIC - Supervisors Application Field and Working Principle

The TSM1121IN PMIC - Supervisors are digital supervisors specifically designed for use in 3.3V, 5V and 12V systems. It provides precise voltage monitoring and has several protection features, such as internal current limited short circuit protection and an external short circuit protection. It is available in an 8-pin or 14-pin SOIC package, with an operating temperature range of -55°C to 125°C.

The TSM1121IN utilizes an internal voltage monitor circuit to measure an external voltage and provide precision voltage regulation. This monitor is triggered by an external digital signal, allowing the TSM1121IN to detect both over-voltage and under-voltage conditions. When the monitored voltage is lower than the set threshold, the TSM1121IN will switch on an external FET or other protection device to prevent damage to the system.

The TSM1121IN also provides an external current limited short circuit protection, which prevents the external FET or other protection device from being damaged due to an over-current situation. It can detect both over-voltage and under-voltage conditions and will shut down the system to prevent further damage.

The TSM1121IN PMIC - Supervisors are ideal for a variety of applications, including LED lighting, embedded systems, mobile devices and Automotive electronics. It is designed to be extremely efficient, with low Quiescent Current (QC) and low total harmonic distortion (THD). It also features auto-restore for a safe and reliable system, and is compatible with a wide range of external digital controllers.

The TSM1121IN is capable of high performance operation in all application fields, and provides adjustable voltage regulators, overload protection, short circuit protection and polarity reversal protection. It can also detect bad capacitors and provides a wide range of protection levels, allowing it to be used in a variety of applications.

In addition, the TSM1121IN allows for easy programming via external microcontrollers or controllers, offering a wide range of customization options for users. It features flexible, on-chip I/O and PWM interfaces, as well as a wide range of voltage monitoring and control functions. This makes the TSM1121IN ideal for automated control in all sorts of industrial, commercial and automotive applications.

Overall, the TSM1121IN PMIC - Supervisors provide a reliable, efficient and economical solution for applications in 3.3V, 5V and 12V systems. Its combination of precise voltage monitoring, exceptional performance and wide range of automated control functions make it an ideal choice for all sorts of applications.
