The preset voltage thresholds are digitally configurable for 5%, 7.5%, 10% or 12.5% accumulation tolerances below the nominal operating voltage. The LTC2932 can aswell be configured to adviser up to four adjustable supplies, with the advantage for abrogating voltage ecology by abutting a arresting affiliate amid the abrogating accumulation and buffered advertence instead of ground. All six preset or adjustable channels affection +/-1.5% (max) beginning accurateness over the absolute temperature range. With affirmed blueprint above the -40°C to +125°C temperature range, the LTC2932 can be acclimated in automotive and aggressive applications. The LTC2932’s displace abeyance aeon can be adapted application an alien capacitor and the displace achievement is affirmed to be in the actual accompaniment for VCC as low as 1V. The LTC2932 aswell includes a displace attenuate pin for margining applications. The LTC2932 is absolution alongside two new six-channel configurable supervisors. The LTC2931 offers agnate functionality and performance, while including a babysitter input, adjustable babysitter timer, and a anchored 5% adviser threshold. The LTC2932 and LTC2931 are both offered in 20-pin TSSOP packages. The LTC2930 includes a push-button chiral displace ascribe and uses alone a individual displace achievement for voltage monitoring, and is accessible in a tiny 3mm x 3mm DFN-12 package. All three six-channel admiral draw alone 52uA of accumulation current. The LTC2930, LTC2931, and LTC2932 are accessible today in commercial, industrial, and automotive temperature grades..
