MAX791TCSE

The MAX791TCSE is one member of the MAX791 series which is designed as the microprocessor supervisory circuit with the 50A supply current (makes the
MAX791 ideal for use in portable equipment, while the 6ns chip-enable propagation delay and 250mA output capability (25mA in battery-backup mode) make it suitable for larger, higher-performance equipment.). This MAX791TCSEcan be used in portable/battery-powered equipment, controllers, computers, critical P power monitoring and intelligent instruments.

Features of the MAX791TCSE are:(1)precision 4.65V voltage monitoring;(2)200ms power-OK/reset time delay;(3)independent watchdog timer-preset or adjustable;(4)1A standby current;(5)power switching:250mA output in Vcc mode and 25mA output in battery-backup mode;(6)on-board gating of chip-enable signals:memory write-cycle completion and 6ns CE gate propagation delay;(7)maxcap or supercap compatible;(8)voltage monitor for power-fail or low-battery warning;(9)backup-battery monitor.

The absolute maximum ratings of the MAX791TCSE can be summarized as:(1)Vcc:-0.3V to +6V;(2)VBATT:-0.3V to +6V;(3)all other inputs:-0.3V to (VOUT+0.3 V);(4)Vcc peak:1.0 A;(5)Vcc continuous:250 mA;(6)VBATT peak:250 mA;(7)VBATT continuous:25 mA;(8)GND, BATT ON:100 mA;(9)all other outputs:25 mA;(10)lead temperature (soldering, 10sec):+300°C;(11)storage temperature range:-65°C to +160°C;(12)continuous power dissipation (TA=+70°C) plastic DIP (derate 10.53mW/°C above +70°C):842 mW;(13)continuous power dissipation (TA=+70°C) narrow SO (derate 8.70mW/°C above +70°C):696 mW.
