PMIC (Power Management Integrated Circuit) - Supervisors, such as the TPS3851G18EDRBT, are specialized power management ICs (PMICs) that provide accurate and efficient system control. The TPS3851G18EDRBT is a single package, 8-pin supervisor circuit with a power-on reset function. It products a reset signal if an input voltage falls below a preset threshold. When an output goes low, the reset is terminated.

The TPS3851G18EDRBT’s main application field is embedded systems and personal microcontrollers, as it provides accurate reset control, as well as power-on reset and brownout detection. In addition, its wide operating temperature range allows stable operation in varying temperature environments. With high monitoring accuracy and good noise immunity, it’s suitable for use in all embedded system designs.

The TPS3851G18EDRBT offers four main features. First, it comes with the industry-leading monitoring accuracy, guaranteed to ±1% at 25°C. Second, it offers a wide operating temperature range, from -40°C up to 85°C. Third, it offers a fast response time, the reset is released in 1.5μs and the input voltage is sampled every 100μs. Lastly, it features a robust reset function, providing both active-low and active-high reset.

The working principle of the TPS3851G18EDRBT is simple. It monitors an input voltage and signals when it falls below the preset threshold. When an output goes low, the reset is terminated and the input voltage is restored. When the power is back up, the reset is released in 1.5μs. In addition, the TPS3851G18EDRBT has an automatic power-on reset timing circuit, so that it can be used both as a normal reset IC and as a power-on reset IC.

In summary, the TPS3851G18EDRBT is an efficient and reliable PMIC - Supervisors and is ideal for embedded systems and personal microcontrollers. It has low power consumption, wide operating temperature range, fast response time and improved monitoring accuracy. With robust reset function and automatic power-on reset timing circuit, the TPS3851G18EDRBT is an excellent choice for all embedded system designs.
