Rochester Electronics PMIC - PMIC - Current Regulation/Management - MAX4211FETE MAX4211FETE

The MAX4211FETE is a high-side power and current monitor designed for applications requiring accurate measurement of load current and power consumption. It features a high-side current-sense amplifier, a 1.21V bandgap reference, and two comparators with open-drain outputs for detecting overpower, overcurrent, and overvoltage conditions. The device supports a wide input source voltage range of +4V to +28V and operates with a power supply voltage range of +2.7V to +5.5V. The MAX4211FETE offers three gain options for the current-sense amplifier: 16.67V/V, 25.00V/V, and 40.96V/V, allowing flexibility in design. It is specified for an extended operating temperature range of -40¬8C to +85¬8C, making it suitable for various environments. The device is available in a compact 16-pin thin QFN package, which is advantageous for space-constrained applications. With a maximum current-sense accuracy of ¬±1.5% and a low supply current of 1.1mA, the MAX4211FETE is well-suited for battery-powered systems and real-time monitoring applications.
