Voltage Detectors in 4-Bump (2 X 2) Chip-Scale Package
General Description
The MAX6406MAX6411 is a family of ultra-low power circuits used for monitoring battery, power-supply, and regulated system voltages. Each detector contains a p r e c i s i o n bandgap reference comparator and is t r i m m e d to specified trip threshold voltages. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring system voltages from 2.5V to 5.0V. A manual reset input is also included. The MAX6406MAX6411 assert a signal whenever the V C C s u p p l y voltage falls below a preset threshold. These devices are differentiated by their output logic c o n f i g u r a t i o n s and preset threshold voltages. The M A X 6 4 0 6 / M A X 6 4 0 9 (push-pull) and the MAX6408/ MAX6411 (open-drain) have an active-low output (OUT is logic low when VCC is below VTH). The MAX6407/ MAX6410 have an active-high push-pull output (OUT is logic high when VCC is below VTH). All parts are guaranteed to be in the correct output logic state for VCC down to 1V. The detector is designed to ignore f a s t transients on V C C . The MAX6406/MAX6407/ MAX6408 have voltage thresholds between 2.20V and 3 . 0 8 V in approximately 100mV increments. The MAX6409/MAX6410/MAX6411 have voltage thresholds b e t w e e n 3.30V and 4.63V in approximately 100mV increments. Ultra-low supply current of 500nA (MAX6406/MAX6407/ MAX6408) makes these parts ideal for use in portable e q u i p m e n t . These devices are available in 4-bump chip-scale packages (UCSP).

The MAX6406MAX6411 are available in factory-set VCC detector thresholds from 2.20V to 4.63V, in approximately 0.1V increments. Choose the desired threshold suffix from Table 1 and insert it in the blank space following "S". There are 21 standard versions with a required order increment of 2500 pieces. Sample stock is generally held on the standard versions only (Table1). Required order increment is 10,000 pieces for nonstandard versions (Table 2). Contact factory for availability. All devices available in tape-and-reel only. UCSP reliability is integrally linked to the user's assembly methods, circuit board material, and environment. Refer to the UCSP Reliability Notice in the UCSP Reliability section of this data sheet for more information. Pin Configuration appears at end of data sheet.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
