Semtech Debuts High-Density Pin Electronics Solution for Burn-in and Low Cost Testers

December 27, 2006 by Jeff Shepard

Semtech Corp. announced the E7802 dual channel driver + window comparator product to address the challenges of next generation, cost-sensitive and high-density ATE applications. The E7802 features two channels of high-current drivers and window comparators in a tiny 5mm x 5mm QFN package for small per-channel footprint. It has an exposed heat slug for superior thermal management and electrical characteristics, enabling it to operate at high currents over a wide operating voltage range.

Each low-overshoot, high-current driver is capable of providing up to 200mA of current and 3.6A of surge current, making the E7802 suitable for driving many devices under test (DUTs) in parallel to help reduce the overall cost of test for test during burn-in (TDBI) applications. Driver high and low level programming is independent for each channel, allowing signal swings with amplitudes from 200m to 15V to be programmed independently over a -3.6 to +15V range at data rates beyond 50MHz (100 Mbps).

Each window comparator channel has been optimized to ensure less than 3ns of propagation delay variation and superior small signal swing/low-overdrive performance. Operating over a wide -2 to +12V common mode range at data rates beyond 100MHz (200Mbps), these comparators have plenty of bandwidth to meet the demands of next generation burn-in and low cost testers. The E7802 was designed to be a robust, pin electronics solution, and the company claims it is the only product in its class to offer driver over-current protection combined with on-chip ESD protection rated in excess of 2kV human body model (HBM) and 500V charged device model (CDM).

The E7802 is now available and is priced at $4.61 each in 1,000-piece lots. The order code for the part is E7802ALPT. Evaluation modules are also available and can be ordered by using the order code EVM7802ALPT. The E7802 is a lead-free product and is RoHS compliant.
