Power management integrated circuits (PMICs) are widely used in a wide variety of applications, from consumer electronics to automotive. Supervisors are a type of PMIC that monitors supply voltages and detects any abnormality. This article will discuss the application field and working principle of S-80850CLMC-B7BT2G, which is one of the most popular supervisors.

S-80850CLMC-B7BT2G belongs to a series of three-terminal voltage supervisors introduced by Semtech Corporation. This series is optimized for a wide range of circuit designs and has excellent voltage detection in several characteristics such as power-on reset, supply brown out, and under voltage lock out (UVLO). It is available in several packages, including SOT-23, USON 6-pin, or Micro SMD.

S-80850CLMC-B7BT2G is designed for applications with a supply voltage up to 6.4V, making it ideal for automotive, industrial, medical, and consumer applications. It also has a low input current of about 0.1μA, low power consumption for its operating range, and a wide temperature range of -40 to +125°C. Its integrated hysteresis allows it to detect any voltage drop or excess that may occur in the circuit while actively running.

The working principle of S-80850CLMC-B7BT2G can be divided into two stages. The first stage is start-up detection, which occurs when the input voltage is applied. Once the start-up voltage (typically 2.7V, but adjustable to 6.4V) is above the threshold voltage, the device outputs a high signal to the RESET_B pin, asserting the reset signal. The second stage is the monitor stage, in which the device constantly monitors the voltage level to determine whether it is within the safe operating range. If the input voltage drops below the threshold level, the RESET_B output will be pulled low, activating the reset signal. This ensures that any glitches or unexpected voltage drops are not overlooked, ensuring the safe operation of the circuit.

In conclusion, S-80850CLMC-B7BT2G is a three-terminal voltage supervisor designed for a wide range of topologies. It has excellent characteristics, such as low power consumption, wide operating temperature range, and low input current. Its two-stage operation ensures the circuit is sufficiently protected from any irregularities in the supply voltage. Because of these features, it is one of the most popular supervisors available in the market today.
