MAX699CWE+

The MAX699CWE+ is a low cost, power-on reset and watchdog controller in 16 pin WSOIC package. The device monitors +5V supply in microprocessor (μP) and digital systems. It supplies a RESET (complementary) pulse of at least 140ms duration on power-up, power-down and during low voltage brownout conditions. Circuit reliability is increased at reduced cost by eliminating all external components and adjustments. It also provides a watchdog input to monitor microprocessor activity. The RESET (complementary) output goes low if the watchdog input (WDI) is not toggled within 1 second. The watchdog feature can be disabled by leaving WDI open. Typical applications include intelligent instruments, controllers, computers and critical & µP power monitoring.

• Supply voltage range is 3V to 5.5V
• Operating temperature range from 0°C to 70°C
• Precision voltage monitor
• Power-OK/reset time delay
• Minimum component count
• Supply current is 5mA
