19-2531; Rev 2; 12/05 Low-Power Dual-/Triple-Voltage SC70 µP Supervisory Circuits MAX6736­MAX6745 General Description Features The MAX6736­MAX6745 are low-power dual-/triple- Dual-/Triple-Supply Reset Voltage Monitors voltage microprocessor (µP) supervisors. These Precision Factory-Set Reset Thresholds for devices assert a reset if any monitored supply falls Monitoring from 0.9V to 5.0V below its factory-trimmed or adjustable threshold andmaintain reset for a minimum timeout period after all Adjustable Reset Input Down to 0.488V supplies rise above their thresholds. The integrated 150ms and 1200ms (min) Reset Timeout Period dual/triple supervisory circuits significantly reduce size Options and power compared to separate ICs or discrete com- VCC1 Power-OK Output for Power-Supply ponents. The low supply current of 6µA makes these Sequencing Applications (MAX6741/MAX6744) devices ideal for portable equipment. Power-Fail Input/Power-Fail Output The MAX6736/MAX6737 are dual fixed-voltage µP (MAX6742/MAX6745) supervisors with a manual reset input. The MAX6738/ MAX6739 have one fixed and one adjustable reset 6µA Supply Current threshold and a manual reset input. The MAX6740/ Tiny SC70 Package MAX6743 are triple-voltage µP supervisors with twofixed and one user-adjustable reset threshold inputs. Ordering Information The MAX6741/MAX6744 are dual-voltage µP supervi-sors with a power-OK (POK) output ideal for power- PART TEMP RANGE PIN-PACKAGE supply sequencing. The MAX6742/MAX6745 monitor MAX6736XK_ _D_-T -40°C to +85°C 5 SC70-5 the primary VCC supply and have an independent MAX6737XK_ _D_-T -40°C to +85°C 5 SC70-5 power-fail comparator. Note: The first "_ _" or "_" are placeholders for the threshold The MAX6736­MAX6745 monitor I/O supply voltages voltage levels of the devices. Desired threshold levels are set (VCC1) from 1.8V to 5.0V and core supply voltages by the part number suffix found in Tables 1 and 2. The "_" after (VCC2) from 0.9V to 3.3V with factory-trimmed reset the D is a placeholder for the reset timeout period suffix found threshold voltage options (Table 1). An external
