STM805LM6E application field and working principle

The STM805LM6E is a highly integrated PMIC (power management IC) or supervisor IC that provides the necessary voltage and current regulation for portable, battery powered applications. This device offers a wide range of features including dynamic voltage scaling, over temperature shut off, over current protection, brown out protection and adjustable over voltage protection.

The STM805LM6E is well suited for medical, consumer, industrial and military applications. It provides 32V of power, supports up to 12V battery input and provides up to 4.5A of output current.

The device is optimized to reduce quiescent current and supports a wide temperature range of -40 to +85°C, making it suitable for harsh environments. It is available in Pb-free and RoHS compliant packages.

The STM805LM6E has two wide input/output voltage range options: 2.3-3.3V/2.3-5.5V or 3.3-6.5V/4.5-7.5V.

The PMIC comes with integrated power management functions such as dynamic voltage scaling (dVS), overvoltage protection (OVP), over current protection (OCP) and brown out protection (BOP). It also has a programmable voltage monitor (PVM) to detect logic supply voltage conditions.

The STM805LM6E has integrated linear regulators for voltage regulation and low noise operation. A range of protection features improve system stability and reduce component count. The PMIC supports up to 12V battery input and up to 4.5A of output current.

The device has diagnostic functions to monitor the condition of the system, including over temperature detection, under voltage detection and over voltage detection.

The STM805LM6E also has auto adjustable output voltage control, temperature compensation, margining and pre-bias startup.

The number of clock cycles required for pre-bias startup can be programmed. This means that the device can be used in applications where the system is powered on from cold start.

Overall, the STM805LM6E is an ideal choice for applications that require high system reliability and accuracy.

In summary, the STM805LM6E is a highly integrated PMIC or supervisor IC that provides a wide range of features and is suitable for a variety of mission critical applications. It features dynamic voltage scaling, over temperature shut off, over current protection and adjustable over voltage protection. It is available in Pb-free and RoHS compliant packages and supports up to 12V battery input and up to 4.5A of output current.
