MAX6738XKRD3-T中文资料美信数据手册PDF规格书

General Description

The MAX6736–MAX6745 are low-power dual-/triple-voltage microprocessor (µP) supervisors. These devices assert a reset if any monitored supply falls below its factory-trimmed or adjustable threshold and maintain reset for a minimum timeout period after all supplies rise above their thresholds. 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.
