MAX1232ESA+T

The MAX1232ESA+T is a microprocessor (μP) monitor in 8 pin NSOIC package. This supervisory circuit provides μP housekeeping and power supply supervision functions while consuming only 1/10th power of DS1232 device. The MAX1232 enhances circuit reliability in μP systems by monitoring power supply, monitoring software execution and providing a debounced manual reset input. The MAX1232 is a plug-in upgrade of Dallas DS1232 device. A reset pulse of at least 250ms duration is supplied on power-up, power-down and low-voltage brownout conditions (5% or 10% supply tolerances can be selected digitally). It also has debounced manual reset input that forces reset outputs to their active states for a minimum of 250ms. A digitally programmable watchdog timer monitors software execution and can be programmed for timeout settings of 150ms, 600ms or 1.2s. The MAX1232 requires no external components and it is used in computers, controllers, intelligent instruments and critical μP power monitoring.

• Supply voltage range from 4.5V to 5.5V
• Operating temperature range from -40°C to 85°C
• VCC trip point of 4.62V (5%) and 4.37V (10%)
• Reset active time of 610ms
