New from Maxim are the MAX16065/ MAX16066, Flash-configurable sequencers/monitors that simplify power management and help conserve power consumption. The devices eliminate the need for external current-sense amplifiers to monitor current and thus save both space and cost. Each device can be programmed for monitoring and sequencing system voltages. The MAX16065 manages up to 12 supply voltages simultaneously, and the MAX16066 manages up to eight supply voltages.
These sequencers/monitors integrate ±2,5% accurate current monitoring and group sequencing to monitor and conserve power. They also feature an analog-to-digital converter (ADC) and non-volatile fault registers to store and read back fault data. An easy-to-use graphical configuration tool eliminates the need for time-consuming programming of complex devices like programmable logic devices (CPLDs) and microprocessors.
The devices provide ±1% accurate voltage monitoring and sequencing for complex systems where high reliability is critical. Their group-sequencing feature lets designers customise and enable different application functions at different times. System functions can be programmed to operate while other functions are disabled. Activating selected functions at programmed intervals and turning off/disabling a secondary set of functions allows the designer to manage power intelligently.
The MAX16065/MAX16066 have a wide 2,8 V to 14 V operating voltage range, which allows operation directly from an intermediate bus voltage. The devices are fully specified over the -40°C to +85°C extended temperature range. The MAX16065 is available in a 48-pin, 7 x 7 mm TQFN package; the MAX16066 is available in a 40-pin, 6 x 6 mm TQFN package.
