Device Description A. General The MAX803 is a microprocessor (P) supervisory circuit used to monitor the power supplies in P and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V powered circuits. This circuit performs a single function: it asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The MAX803 has an open-drain output stage. The MAX803's open-drain RESET-bar output requires a pull-up resistor that can be connected to a voltage higher than VCC. The MAX803 has an activelow RESET-bar output. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1V. Low supply current makes the MAX803 ideal for use in portable equipment. The MAX803 is available in a 3-pin SC70 package.

B. Outgoing Inspection Level:
C. Observed Outgoing Defect Rate: < 50 ppm D. Sampling Plan: Mil-Std-105D VI. Reliability Evaluation A. Accelerated Life Test The results of the 135C biased (static) life test are shown in Table 1. Using these results, the Failure Rate () is calculated as follows: = 1= MTTF 1.83 (Chi square value for MTTF upper limit) 192 x 4340 x 160 x 2 Temperature Acceleration factor assuming an activation energy of 0.8eV = 6.87 x 10-9 = 6.87 F.I.T. (60% confidence level @ 25C)
This low failure rate represents data collected from Maxim's reliability monitor program. In addition to routine production Burn-In, Maxim pulls a sample from every fabrication process three times per week and subjects it to an extended Burn-In prior to shipment to ensure its reliability. The reliability control level for each lot to be shipped as standard product is 59 F.I.T. at a 60% confidence level, which equates to 3 failures in an 80 piece sample. Attached Burn-In Schematic (Spec. #06-5033) shows the static Burn-In circuit. Maxim performs failure analysis on any lot that exceeds this reliability control level. Maxim also performs quarterly 1000 hour life test monitors. This data is published in the Product Reliability Report (RR-1N). Current monitor data for the B8/S8 Process results in a FIT rate of 0.17 @ 25C and 2.92 @ 55C (eV = 0.8, UCL = 60%).
B. Moisture Resistance Tests Maxim pulls pressure pot samples from every assembly process three times per week. Each lot sample must meet an LTPD = 20 or less before shipment as standard product. Additionally, the industry standard 85C/85%RH testing is done per generic device/package family once a quarter. C. E.S.D. and Latch-Up Testing The MS42 die type has been found to have all pins able to withstand a transient pulse of 2500V, per Mil-Std-883 Method 3015 (reference attached ESD Test Circuit). Latch-Up testing has shown that this device withstands a current of 250mA.
