Manufacturer

Description

The X40030, X40031, X40034, X40035 combine power-on reset control, watchdog timer, supply voltage supervision, second and third voltage supervision, and manual reset, in one package. This combination lowers system cost, reduces board space requirements, and increases reliability.

Features
• Triple voltage detection and reset assertion
   - Standard reset threshold settings; see Table 1 on page 5.
   - Adjust low voltage reset threshold voltages using special programming sequence
   - Reset signal valid to VCC = 1V
   - Monitor three separate voltages
• Fault detection register
• Selectable power-on reset time-out (0.05s, 0.2s, 0.4s, 0.8s)
• Selectable watchdog timer interval (25ms, 200ms, 1.4s or off)
• Debounced manual reset input
• Low power CMOS
   - 25µA typical standby current, watchdog on
   - 6µA typical standby current, watchdog off
• 400kHz 2-wire interface
• 2.7V to 5.5V power supply operation
• Available in 14 Ld SOIC and 14 Ld TSSOP packages
• Monitor voltages: 5V to 0.9V
• Independent core voltage monitor
• Pb-free available (RoHS compliant)

Applications
• Communication equipment
   - Routers, hubs, switches
   - Disk arrays, network storage
• Industrial systems
   - Process control
   - Intelligent instrumentation
