Maxim Integrated introduces the MAX16089XS46L+T application field and working principle, an advanced, cost-optimized power management integrated circuit (PMIC). It is designed for cost-sensitive, medium-power applications in consumer, industrial, computing, and communication markets. The device offers a wide range of features such as a power-on reset circuit, brownout reset, power sequencer, and voltage supervisors. It also provides a highly efficient, low-noise, low-cost switch-mode step-up DC-DC converter, wide input voltage range, low standby current, and programmable output voltage.

The MAX16089XS46L+T incorporates a precision voltage supervisor and power-on reset (POR) circuit that effectively monitor the system voltage levels, allowing the device to recognize the exact power-up sequence. It will accurately detect and respond to dynamic VCC levels using its innovative adaptive window comparison technique. In addition, the MAX16089XS46L+T features a brownout reset (BOR) circuit and a flexible programmable startup sequence, allowing designers to determine an optimized sequence for the system.

The voltage monitoring circuit in the MAX16089XS46L+T provides two user-configurable voltage thresholds (Vt_HIGH and Vt_LOW) with an adjustable timeout period. This allows users to set desired trip points and power-up/down sequences during system operations, and define the timing of the power sequence. The voltage monitoring circuit also offers a watchdog timer function to detect, and respond to, inactivity or failure of system circuitry.

The MAX16089XS46L+T provides a highly efficient, low-noise, low-cost, externally switched step-up DC-DC converter. The device can optimize system performance by providing a wide input voltage range of 2.7V to 20V, resulting in improved efficiency and higher power performance.

The device also features a low quiescent current which allows higher system availability, higher throughput, and improved power efficiency. Additionally, a wide range of optional clock frequencies and output voltage swing of up to 1.85V during the startup sequence enable the device to be easily adapted to any system.

Overall, the MAX16089XS46L+T is a low-cost, high-performance PMIC that provides superior reliability and performance to meet the demands of cost-sensitive, medium-power applications. It offers an accurate voltage monitoring and watchdog timer function, a highly efficient step-up DC-DC converter, low standby current, and programmable output voltage, making it an ideal choice for applications in consumer, industrial, computing, and communication markets.
