Maxim Integrated MAX6412UK16 - Low-Power, Miniature Microprocessor Reset Circuits
The MAX6412UK16 from Maxim Integrated is a compact and reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides a robust solution for system monitoring, ensuring that the µP resets properly during a power failure. This high-quality component is an essential addition to any digital system requiring stable and secure operation.
With its tiny SOT23-5 package, the MAX6412UK16 is ideal for space-constrained applications. It boasts a low quiescent current of only 1.5µA, making it an excellent choice for battery-operated devices where power efficiency is critical. The device operates over a wide voltage range, from 1.2V to 5.5V, and features a factory-trimmed reset threshold voltage of 1.6V, ensuring precise monitoring of the system voltage without the need for external components.
The MAX6412UK16 offers several key features that enhance system reliability. Its reset output is guaranteed to be in the correct state for V_CC down to 1V, and it can assert a reset signal for a minimum of 140ms (typical) after V_CC has risen above the reset threshold level. This ensures that the µP has sufficient time to stabilize before resuming operation. Additionally, the device's built-in debouncing capability handles noisy inputs, which can be critical in electrically noisy environments.
Designed with versatility in mind, the MAX6412UK16 caters to a wide range of applications including portable/battery-powered equipment, computers, controllers, intelligent instruments, critical µP and µC power monitoring, and embedded systems. Its manual reset capability allows for a reset to be asserted at any time by the user or an external signal, providing an additional layer of control.
To summarize, the MAX6412UK16 from Maxim Integrated is a high-performance, low-power reset circuit that delivers reliable and precise monitoring for digital systems. Its miniature footprint, low power consumption, and robust feature set make it an indispensable component for ensuring the stability and security of microprocessor-based applications.
