MAX1587CETL+

Introduction

The MAX1587CETL+ is a high performance power management integrated circuit (PMIC). It integrates an intelligence controller, multiple power stages and advanced features, making it ideal for automotive, personal and industrial applications demanding reliable, robust power solution.

Application Fields and Working Principle

The MAX1587CETL+ provides ultra-low quiescent current to achieve the low fuel consumption requirements of the EV/HEV automotive powertrain, while meeting the load-dump, over-temperature and over-voltage protection requirements of a wide range of automotive applications. It also offers a 12V 3A gate drive to supply both high-side and low-side Mosfets, as well as a high-current gate driver for higher load demands. This allows significant power savings while ensuring robustness and long-term reliability. Furthermore, the device provides advanced protection features such as Over-Voltage Lock Out (OVLO) and Under-Voltage Lock Out (UVLO), which automatically shut down the device when protection parameters are exceeded.

The MAX1587CETL+ provides current-mode control and uses peak current-mode control to provide fast transient response at all load current levels. The device also provides traditional pulse-width modulation (PWM) and pulse frequency modulation (PFM) modes to enable further power saving. The device has a peak current-limit feature, which enables higher output current than the conventional constant-current limit mode for improved efficiency. Additionally, it also features an over-temperature protection which shuts down the device when critical device temperature is reached.

Conclusion

The MAX1587CETL+ is a highly integrated power management IC, specifically designed to meet the requirements of automotive, personal and industrial applications. It integrates an intelligence controller, multiple power stages and advanced features, such as OVLO, UVLO and over-temperature protection, making it ideal for applications demanded reliable and robust power solution. The device offers excellent transient response and high current capacity, as well as the traditional PWM and PFM modes for further power saving.
