Maxim Integrated MAX16082XR38W+T Voltage Supervisor IC

The MAX16082XR38W+T is a compact, highly reliable voltage supervisor IC designed by Maxim Integrated to ensure the proper operation of microprocessors (µPs), microcontrollers (MCUs), and other voltage-sensitive devices. This supervisory circuit monitors the system voltage and maintains a reset signal to the host processor until that voltage reaches a stable and accurate threshold, thereby safeguarding the system from unpredictable behavior during power-up, power-down, and brown-out conditions.

One of the standout features of the MAX16082XR38W+T is its factory-trimmed reset threshold voltage, set at 3.8V, which is ideal for systems operating at standard logic levels. The device operates over a wide range of supply voltages, from 1.0V to 5.5V, providing versatility for various application requirements.

The MAX16082XR38W+T also boasts an impressive low quiescent current, typically around 1.6µA, making it an energy-efficient choice for battery-powered and portable applications where power conservation is critical. Additionally, its small form factor, available in a tiny, 4-bump, 0.86mm x 1.36mm WLP (wafer-level package), allows for high-density board designs and saves precious board space in space-constrained applications.

This voltage supervisor IC includes several key features that enhance system reliability and performance, such as:

• Manual Reset Input: Provides an external override to initiate a system reset, allowing for additional system-level control.
• Open-Drain Reset Output: Allows for the flexibility to interface with a variety of logic levels and the option to wire-OR multiple devices.
• Power-Supply Transient Immunity: Ensures stable operation during supply voltage transients, avoiding false resets and maintaining system integrity.
• Immunity to Short VCC Transients: Protects against brief voltage dips that could otherwise cause unintended system resets.

The MAX16082XR38W+T is an ideal solution for applications that require precise voltage monitoring and robust protection features, such as portable devices, embedded systems, and industrial equipment. With its precision voltage monitoring and low-power consumption, this voltage supervisor IC from Maxim Integrated is a dependable component for maintaining system stability and reliability.
