Description

DESCRIPTION
The X40010/11/14/15 combines power-on reset control, watchdog timer, supply voltage supervision, and secondary voltage supervision, in one package. This combination lowers system cost, reduces board space requirements, and increases reliability.

FEATURES
• Dual voltage detection and reset assertion
   —Standard reset threshold settings See Selection table on page 2.
   —Adjust low voltage reset threshold voltages using special programming sequence
   —Reset signal valid to VCC = 1V
   —Monitor three voltages or detect power fail
• Independent Core Voltage Monitor (V2MON)
• Fault detection register
• Selectable power on reset timeout (0.05s, 0.2s, 0.4s, 0.8s)
• Selectable watchdog timer interval (25ms, 200ms,1.4s, off)
• 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 packages
   —8-lead SOIC, TSSOP
• Monitor Voltages: 5V to 0.9V
• Independent Core Voltage Monitor
