Rad-Hard, 5.0V/3.3V µ-Processor Supervisory Circuits

ISL705AEH, ISL705BEH, ISL705CEH, ISL706AEH, ISL706BEH, ISL706CEH

This family of devices are radiation hardened 5.0V/3.3V

supervisory circuits that reduce the complexity required to

monitor supply voltages in microprocessor systems. These

devices significantly improve accuracy and reliability relative to

discrete solutions. Each IC provides four key functions.

Features

• Electrically Screened to SMD 5962-11213

• QML Qualified per MIL-PRF-38535 Requirements

• Radiation Hardness

1. A reset output during power-up, power-down, and brownout

conditions.

- High Dose Rate. . . . . . . . . . . . . . . . . . . . . . . . . . 100krad(Si)

- Low Dose Rate . . . . . . . . . . . . . . . . . . . 100krad(Si) (Note 1)

2. An independent watchdog output that goes low if the

watchdog input has not been toggled within 1.6s.

- SEL/SEB LET . . . . . . . . . . . . . . . . . . . . 86MeV * cm /mg

• Precision Supply Voltage Monitor

3. A precision threshold detector for monitoring a power

- 3.08V Threshold in the ISL706AEH/BEH/CEH

• 200ms (Typ) Reset Pulse Width

supply other than V

4. An active-low manual-reset input.

Specifications for Rad Hard QML devices are controlled by the

Defense Logistics Agency Land and Maritime (DLA). The SMD

numbers listed in the “Ordering Information” table on page 3

must be used when ordering.

- Active High, Active Low and Open Drain Options

• Independent Watchdog Timer with 1.6s (Typ) Timeout

• Precision Threshold Detector

Detailed Electrical Specifications for the ISL705AEH,

ISL705BEH, ISL705CEH, ISL706AEH, ISL706BEH and

ISL706CEH are contained in SMD 5962-11213. A “hot-link” is

also provided on our website for downloading.

- 1.25V Threshold in the ISL705AEH/BEH/CEH

- 0.6V Threshold in the ISL706AEH/BEH/CEH

• Debounced TTL/CMOS Compatible Manual-Reset Input

• Reset Output Valid at V = 1.2V
