Description : SC70/µDFN, Single/Dual Low-Voltage, Low-Power µP Reset Circuits

General Description
The MAX6381–MAX6390 microprocessor (µP) supervisory circuits monitor power-supply voltages from +1.8V to +5.0V while consuming only 3µA of supply current at +1.8V. Whenever VCC falls below the factory-set reset thresholds, the reset output asserts and remains asserted for a minimum reset timeout period after VCC rises above the reset threshold. Reset thresholds are available from +1.58V to +4.63V, in approximately 100mV increments. Seven minimum reset timeout delays ranging from 1ms to 1200ms are available.

Description : Ultra-Small, Ultra-Low Power MEMS Oscillator with Spread Spectrum for Automotive

General Description
The DSA63xx series of clock generators uses a proven silicon MEMS technology to provide excellent frequency sTability over a wide range of temperatures as well as small size. Available in three different package sizes with operating current as low as 3 mA, the smallest 4-pin package is a mere 1.6 mm x 1.2 mm in size. The devices support up to ±2.5% or –3% spread spectrum that can achieve up to 15 dB electromagnetic interference (EMI) reduction.

Description : Low-Power Dual-/Triple-Voltage SC70 µP Supervisory Circuits

General Description
The MAX6736–MAX6745 are low-power dual-/triple-voltage microprocessor (µP) supervisors.

The integrated dual/triple supervisory circuits significantly reduce size and power compared to separate ICs or discrete components. The low supply current of 6µA makes these devices ideal for porTable equipment.
