The X4003 and X4005 CPU Supervisors combine power-on reset control, watchdog timer, and supply voltage supervision in a single device. This integration reduces system cost, board space, and increases reliability.
Key Features
Selectable watchdog timer with three preset time-out intervals (200ms, 600ms, 1.4s) or off.
Low Vcc detection and reset assertion with five standard reset threshold voltages (4.62V, 4.38V, 2.92V, 2.68V, 1.75V) and adjustable threshold using a special programming sequence.
Low power CMOS with 12μA typical standby current (watchdog on), 80nA typical standby current (watchdog off), and 3mA active current.
40kHz I2C interface and 1.8V to 5.5V power supply operation.
Available in 8-lead SOIC and MSOP packages, with Pb-free options.
