The MAX6406-MAX6411 is a family of ultra-low power circuits used for monitoring battery, power-supply, and regulated system voltages. Each detector contains a precision bandgap reference comparator and is trimmed 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 MAX6406-MAX6411 assert a signal whenever the VCC supply voltage falls below a preset threshold. These devices are differentiated by their output logic configurations and preset threshold voltages. The MAX6406/MAX6409 (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 fast transients on VCC. The MAX6406/MAX6407/ MAX6408 have voltage thresholds between 2.20V and 3.08V in approximately 100mV increments. The MAX6409/MAX6410/MAX6411 have voltage thresholds between 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 equipment. These devices are available in 4-bump chip-scale packages (UCSP).
The MAX6406-MAX6411 is a family of ultra-low power circuits designed for monitoring battery, power-supply, and regulated system voltages. These devices feature a precision bandgap reference comparator and are factory-trimmed to specified trip threshold voltages between 2.5V and 5.0V.
The detectors assert a signal when the Vcc supply voltage falls below a preset threshold and include a manual reset input. They are available in three output logic configurations: active-low push-pull, active-high push-pull, and active-low open-drain. The devices operate with an ultra-low 500nA supply current (for MAX6406-MAX6408) and require no external components.
| Supply Current (MAX6406/MAX6407/MAX6408) | 500nA |
|---|---|
| Threshold Accuracy | +/-2.5% |
| Operating Temperature Range | -40°C to +85°C |
| Package Type | UCSP-4 (Chip-Scale Package) |
The supply current for these models is an ultra-low 500nA.
The devices offer active-low push-pull, active-high push-pull, and active-low open-drain outputs.
No, they eliminate the need for external components and adjustments.
