The X4003 and X4005 are CPU supervisors that combine power-on reset control, watchdog timer, and supply voltage supervision. These devices lower system cost, reduce board space requirements, and increase reliability.
Key Features:
Selectable watchdog timer with three preset values: 200ms, 600ms, and 1.4s
Low Vcc detection and reset assertion with five standard reset threshold voltages: 4.62V, 4.38V, 2.92V, 2.68V, and 1.75V
Adjustable low Vcc reset threshold voltage using a special programming sequence
Low power CMOS with 12μA typical standby current (watchdog on) and 80nA typical standby current (watchdog off)
40kHz I2C interface and 1.8V to 5.5V power supply operation
Package Options:
Available in 8 Ld SOIC and 8 Ld MSOP packages, with Pb-free options available.
