Maxim Releases Microprocessor Supervisory Circuits

Maxim Integrated Products has introduced its MAX16060/MAX16061/MAX16062 1% accurate, quad-/hex-/octal-voltage microprocessor supervisors. Offering accurate monitoring, these devices maximize system reliability. To achieve this accuracy, they integrate a bandgap reference that enables highly precise trimming of the voltage thresholds. Setting the industry benchmark for accuracy and integration, the MAX16060/MAX16061/MAX16062 are ideal for precision monitoring of complex multivoltage systems such as those found in networking, storage, and telecom equipment. The quad-/hex-/octal-voltage monitors are offered in various combinations of factory-fixed or user-adjustable voltage thresholds. The factory-fixed thresholds are available for monitoring standard 3.3V, 2.5V, and 1.8V voltages, while user-adjustable thresholds can monitor down to 0.4V. Thus, a single IC can employ all adjustable thresholds or a combination of fixed and adjustable thresholds for precision voltage monitoring. The user can select from factory-fixed or adjustable reset-timeout options.



The MAX16060/MAX16061/MAX16062 also include independent outputs for each monitored voltage, an active-low reset output, a manual-reset input, a fixed or capacitor-adjustable reset timeout, and a watchdog timer. Other supervisory features include a tolerance-select input for selecting 5% or 10% input thresholds, and a margin-enable function for deasserting the outputs during margin testing. The MAX16060/MAX16061/MAX16062 are fully specified over the -40 degrees Celsius to +125 degrees Celsius automotive temperature range, and are available in small, 4mm x 4mm TQFN packages. Prices start at $3.73 (1000-up, FOB USA).
