Driver/comparator cuts space for ATE
Dual-channel driver and window comparator addresses the challenges of next generation, cost-sensitive and high-density ATE applications.
Semtech Corp has announced the E7802 dual-channel driver and window comparator 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 5 x 5mm QFN package for the smallest per-channel footprint on the market

Low-cost miniature push-pull voltage controller
New from Semtech, the SC4820 is a low-power pulsewidth modulator (PWM) controller intended for power conversion using push-pull or bridge topologies.
Linear FET controllers for space-saving PSU design
Semtech has a new family of linear FET controllers that enable simple, space-saving design of distributed single and dual power supplies on primary and peripheral circuit boards.
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 perfect 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 200mV to 15V to be programmed independently over a -3.6 to +15V range at datarates beyond 50MHz (100Mbit/s).

High-density ATE pin-electronics chipset
Semtech has released a new high-performance high-density pin-electronics chipset for use in automated test equipment.
Each window comparator channel has been optimised 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 datarates beyond 100MHz (200Mbit/s), 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, best-in-class, pin electronics solution and as such 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 the latest member of Semtech's automated test equipment (ATE) standard product offerings which represents the state-of-the-art in general purpose pin electronics.
"The E7802 was defined with a small solution size and affordable test economics in mind", said Tim Wilhelm, Director of Marketing for Semtech's Test and Measurement Division.
"Off the shelf, this dual-channel device offers customers a per-channel solution density that is twice that of quad- or even octal-channel devices with additional features and performance not previously available in this class of pin electronics".
This high density and wide voltage range does not come at the expense of timing accuracy as the E7802 boasts best-in-class timing stability for predictable timing edges that are easily deskewed.
The E7802 is now available and is priced at US $4.61 each in 1000-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.
