EM Microelectronic, a company of the Swatch Group, announces an ultra-low voltage, low-current watchdog IC. The EM6323/24 circuits feature low threshold voltages between 1.31 V and 4.63 V, and operate with power supplies between 1.5 V and 5 V over a temperature range of – 40°C to 125°C. The EM6323/24 achieves a 1.31 V threshold voltage, ultra-low 2.4 uA supply current and is available in 5-pin SOT23 packaging. This reset and watchdog circuit can be used to monitor the power supplies in low-power microprocessors, microcontrollers and digital systems. The EM6323 has all of the features of the EM6324, plus an additional manual reset pin with internal pull-up. Both circuits also send a reset signal to the microprocessor during power-up, power-down and brownout conditions.
