PMIC - Power Supply Controllers, Monitors

The TDA16846HKLA1 is a programmable integrated power controller IC that provides a high degree of flexibility in controlling power supply voltages. The IC features an internal 4096-bit EEPROM memory that allows programmable power voltage settings that integrate controller and monitor functions, such as power good, overvoltage protection, short circuit protection, brown-out protection, and load line regulation. This design ensures that the system will respond correctly to changes in the supply voltage.

The applications available for the TDA16846HKLA1 include industrial, automotive, communications, and medical industries. In the industrial industry, the IC can be used to implement turnkey power solutions for systems used in harsh environments such as mining and oil & gas. The integrated functions of the IC can also be used in automotive applications, such as minimizing power consumption and preventing power loss. It is also ideal for electrical & communications systems as it can provide a cost-effective solution for supplying power to devices with varying requirements. In the medical industry, the IC can be used for numerous applications due to its compactness, efficient operation, and guaranteed reliability.

The TDA16846HKLA1 work on the principle on an integrated power supply designed to deliver a stable and reliable output voltage. The power supply design includes a surge protection circuit to protect against inrush current and instant overload. The output voltage is adjustable within a range, realized with a 6-bit DAC and a control switch to set the output voltage reference. The voltage can be controlled in two ways: with a digitally controlled potentiometer and with a voltage-controlled oscillator. The former allows the user to achieve a smooth transition of the output voltage, the latter continuous control, with a comparatively higher reference current and resolution. For thermal protection, the IC features an internal thermal monitoring circuit and external temperature sensors. These sensors detect changes in ambient temperature, and can actuate a shut down of the IC if the temperature exceeds the preset threshold.

In summary, the TDA16846HKLA1 is an integrated power controller IC that can provide a highly flexible and programmable power supply solution for systems used in a wide range of industries. The IC integrates power regulator, monitor, and protection functions while working on the principle of a voltage-controlled output voltage. The IC is also provided with various integrated thermal protection features to ensure a safe operation in harsh environments.
