Supervisor monitors power supplies as
low as 1.5V
A low-voltage supervisor IC for monitoring power supplies as low as 1.5V has been developed by Micrel Semiconductor.
A low-voltage supervisor IC for monitoring power supplies as low as 1.5V has been developed by Micrel Semiconductor Available in Micrel's IttyBitty SOT235 packaging, the MIC2775 features a choice of factory-programmed voltage options and ultralow quiescent current

World's simplest buck regulator boosted to 2A
Micrel has boosted the output capability of the industry's simplest surface-mount DC/DC switching convertor to 2A while retaining the device's original SO-8 packaging.
Dual and triple 135MHz low-power op amps
Consuming just 2.4mA per op amp, the MIC915 dual and MIC916 triple op amps extend Micrel's premier family of high-speed, low-power op amps for power-sensitive high-speed applications.
"Many existing fixed-voltage supervisor ICs can monitor voltages only as low as 2.5V", says Jim Judkins, Product Marketing Manager.
"The MIC2775, however, can monitor supplies down to 1.5V.
As manufacturers shrink process geometries to make higher-performance, lower-cost CPUs, DSPs, SOCs, memories and ASICs, the voltages required by these devices are dropping rapidly", Judkins continues.
"Logic voltages are already entering the sub-two-volt area, and will likely go lower.
The MIC2775 is an integrated solution for monitoring these supplies".
The MIC2775 is available in a range of factory-programmed voltage options to completely eliminate external components.
The industry-standard package and pinout make it a drop-in upgrade for previous generations of supervisor ICs.
The quiescent power supply current is a portable-friendly 3.5uA.
Both an active-high and an active-low reset output are provided in addition to a manual reset input for a reset switch or for daisychaining onto existing power supervision circuitry.
In 1000 piece quantities, the MIC2775 in Micrel's IttyBitty SOT235 packaging is priced at $0.78 each.
Samples are from stock.
These devices are manufactured using Micrel's proprietary BiCMOS process.
