Voltage Detectors in 4-Bump (2 X 2) Chip-Scale Package
General Description
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 V CC 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 V CC . 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).

Detailed Description
Manual Reset Input
Many P-based products require manual reset capability, allowing the operator, a test technician, or external logic circuit to initiate a reset. A logic low on MR asserts OUT/OUT. OUT/OUT remains asserted while MR is low. This input has an internal 50k pullup resistor, so it can be left open if it is not used. MR can be driven with TTL or CMOS logic levels, or with open-drain/collector outputs. Connect a normally open momentary switch from MR to GND to create a manual reset function. If MR is driven from long cables or if the device is used in a noisy environment, connect a 0.1F capacitor from MR to ground to provide additional noise immunity.

Applications Information
Interfacing to Different Logic Voltage Components
The MAX6408/MAX6411 have an active-low, opendrain output. This output structure will sink current when OUT is asserted. Connect a pullup resistor from OUT to any supply voltage up to 5.5V (Figure 1). Select a resistor value large enough to allow a valid logic low (see Electrical Characteristics), and small enough to register a logic high while supplying all input currents and leakage paths connected to the OUT line.

Negative-Going VCC Transients
These devices are relatively immune to short-duration, negative-going VCC transients (glitches). The Typical Operating Characteristics show the Maximum Transient Duration vs. Threshold Overdrive graph, for which output pulses are not generated. The graph shows the maximum pulse width that a negativegoing V CC transient may typically have before the devices issue output signals. As the amplitude of the transient increases, the maximum allowable pulse width decreases. TRANSISTOR COUNT: 512 PROCESS: BiCMOS
Chip Information
UCSP Reliability
The chip-scale package (UCSP) represents a unique packaging form factor that may not perform equally to a packaged product through traditional mechanical reliability tests. CSP reliability is integrally linked to the user's assembly methods, circuit board material, and usage environment. The user should closely review these areas when considering use of a CSP package. Performance through Operating Life Test and Moisture Resistance remains uncompromised as it is primarily determined by the wafer-fabrication process. Mechanical stress performance is a greater consideration for a CSP package. CSPs are attached through direct solder contact to the user's PC board, foregoing the inherent stress relief of a packaged product lead frame. Solder joint contact integrity must be considered. Information on Maxim's qualification plan, test data, and usage recommendations are detailed in the UCSP application note, which can be found on Maxim's website at www.maxim-ic.com.
