The MAX6892/MAX6893/MAX6894 pin-selectable, multivoltage supply sequencers/supervisors monitor several voltage-detector inputs and one watchdog input, asserting the respective voltage detector or watchdog output when the inputs drop below the configured voltage thresholds or the watchdog timer expires. The MAX6892 features eight voltage detector inputs and 10 outputs. The MAX6893 features six voltage-detector inputs and eight outputs, while the MAX6894 features four voltage detector inputs and six outputs. An active-low RESET output ensures all monitored inputs are above the set thresholds. The voltage detector outputs are configured as open drain. Manual reset and margin disable inputs offer additional flexibility.
The thresholds of the MAX6892/MAX6893/MAX6894 are selected through five logic inputs (TH0–TH4). The logic on these five inputs selects the supply voltage tolerance (5% or 10%) and one of 32 factory-set thresholds settings. Watchdog and reset timeout periods can use factory default settings or are independently adjustable by connecting external capacitors.
When any of the monitored voltages falls below its threshold, the respective output asserts and remains asserted for 6.25ms (typ) after the monitored voltage exceeds the threshold. The outputs can be connected to the shutdown or enable inputs of DC-DC regulators to provide turn-on power sequencing to ensure proper system initialization.
The MAX6892 is available in a 5mm x 5mm x 0.8mm, 32-pin, Thin QFN package, while the MAX6893/MAX6894 are available in a 5mm x 5mm x 0.8mm, 28-pin, Thin QFN package. The MAX6892/MAX6893/MAX6894 are specified to operate over the extended temperature range (-40°C to +85°C).

Evaluation Kits 1
MAX6889EVCMAXQU
Evaluation Kit for the MAX6889/MAX6892
Product Detail
The MAX6889 evaluation system (EV system) consists of a MAX6889 evaluation kit (EV kit) and a Maxim CMAXQUSB command module. The MAX6889/MAX6892 EEPROM-configurable, multivoltage power-supply sequencers/supervisors monitor several voltage-detector inputs, two auxiliary inputs, and four general-purpose logic inputs and feature programmable outputs for highly configurable power-supply sequencing applications. The evaluation software runs under Windows® 98/2000/XP, providing a handy user interface to exercise the features of the MAX6889.
Order the complete EV system (MAX6889EVCMAXQU) for comprehensive evaluation of the MAX6889 using a personal computer. Order the EV kit (MAX6889EVKIT) if the command module has already been purchased with a previous Maxim EV system or for custom use in other microcontroller (µC)-based systems.
This system can also evaluate the MAX6892. Contact factory for a free sample of MAX6892ETJ.
