Intersil Releases ISL6131/ISL6132 Supervisory ICs

Intersil Corp. (Milpitas, CA) announced the release of two new voltage supervisory ICs, the ISL6131 and ISL6132. The tiny, near-chip-scale, packaged ICs monitor and report on voltage conditions for up to four voltage sources above 0.7V. The ISL6131 and ISL6132 are designed for a wide range of applications that include voltage bus monitoring for DSPs, and processors found in embedded control systems, graphics cards, intelligent instruments, network equipment, portable devices, set-top boxes, and telecommunications systems.

The ISL6131 and ISL6132 offer four-channel under-voltage monitoring (ISL6131); two-channel monitoring for over-voltage and under-voltage conditions (ISL6132); resistor-programmable, voltage-monitoring thresholds; a nominal supply voltage of 1.5V to 5.5V; a STATUS/PGOOD time delay of 150ms to ensure stability; open-drain status outputs for interface flexibility; VDD lockout and VDD and VMON glitch immunity; and a 24-pad, 4mm x 4mm, QFN package.

The ISL6131IR and ISL6132IR are available now in the 24-pad, 4mm x 4mm, QFN package rated for the –40°C to +85°C industrial temperature range. The price of each part is $2.65 per IC in 100-unit to 999-unit quantities. Other pricing is available upon request.
