The high-performance HIP6019BCB-T is a linear and switching voltage regulator integrated circuit (IC) from Intersil Corporation that is used in a wide range of application fields. It is an Automotive-grade IC rated for operation up to a supply voltage of 100V and under temperatures of -40°C to +125°C. Due to its advanced features, high accuracy, integrated protection functions, and low quiescent current, the HIP6019BCB-T has great flexibility and makes it an ideal regulator for automotive applications such a an automotive ECU, telemetric system, and charging ICs.

The HIP6019BCB-T is a high-current, 12V regulator and typically provides up to 500mA of output current. It is capable of regulating both positive and negative supply outputs, however, the external components that are combined with the IC will determine the polarity of the output. Its dynamic output impedance is designed to be low, with a maximum impedance of 0.015Ω under a light load and 0.03Ω when at full load. This makes it ideal for high-current stability as it can provide better current supply to the IC. Furthermore, it also has a unique current protection feature which is enabled through the UVLO settings. This helps keep the output current levels within safety specify.

The HIP6019BCB-T has three operating modes: the low-leakage mode, current-limiting mode, and selectable linear mode or switching mode. In the low-leakage mode, the device will draw negligible leakage current from the input source when the output current is low. This helps preserve battery life in automotive application that require lower currents. In the current-limiting mode, the maximum current is clamped, preventing the output from overloading when a fault occurs in the system. The selectable linear mode is capable of providing more than 500mA of output current, at a nominal supply voltage of 12 V up to a 100V. It has an input voltage range of 4.5 V to 12 V, a robust short-term load regulation of ±1% regardless of the load duty cycle or input voltage, and a typical peak-current limit of 800mA.

The switching mode of the IC can boost the output voltage up to around 90V, providing high levels of accuracy and stability. This is achieved through the use of low-dropout (LDO) technology, allowing the output voltage to be tightly regulated over a wide range of supply voltages and load conditions. This mode is useful when dealing with automotive applications such as lighting, as the output voltage requirements tend to be highly variable. Additionally, this feature helps reduce the power losses associated with linear regulations.

In addition to its high current ratings and various modes, the HIP6019BCB-T also comes equipped with an optional brownout detection (BOD) feature. This helps detect when the supply voltage drops to an unsafe level. The device will then switch to the low-leakage mode, protecting the system from further damage. This is especially useful in automotive applications where the supply voltage levels can be highly unpredictable.

The HIP6019BCB-T also contains a number of features designed specifically for improved performance and reliability. It incorporates on-chip protection structures that reduce the risk of electro-static discharges (ESD) and operate at very low quiescent currents for increased efficiency. Furthermore, the IC has an overvoltage protection feature, which will protect both the device itself and other components connected to the regulator from voltage spikes that may occur due to current fluctuations. Combined with the low-leakage mode, the integrated protection functions provide greater levels of reliability and performance.

In summary, the HIP6019BCB-T is a high-performance and highly reliable linear and switching voltage regulator IC suitable for a range of automotive applications such as ECU, telemetric systems, and charging ICs. It is rated for operation up to 100V and under temperatures of -40°C to +125°C, with a maximum output current of 500mA. It has various operating modes, such as the low-leakage mode, current-limiting mode, and selectable linear mode or switching mode. It also features an optional brownout detection feature and a number of integrated protection functions, providing greater levels of reliability and performance.
