Triple Voltage Monitor with Integrated CPU Supervisor

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.

Applying voltage to V

activates the power-on reset circuit,

which holds RESET/RESET active for a period of time. This

allows the power supply and system oscillator to stabilize

before the processor can execute code.

Low VCC detection circuitry protects the user’s system from

low voltage conditions, resetting the system when VCC falls

below the minimum VTRIP1 point. RESET/RESET is active

until VCC returns to proper operating level and stabilizes. A

second and third voltage monitor circuit tracks the unregulated

supply to provide a power fail warning or monitors different

power supply voltage. Three common low voltage

combinations are available, however, Intersil’s unique circuits

allows the threshold for either voltage monitor to be

reprogrammed to meet specific system level requirements or to

fine-tune the threshold for applications requiring higher

precision.

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 V

= 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

• Computer systems
