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.

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.

Detailed Electrical Specifications for the ISL705AEH,

ISL705BEH, ISL705CEH, ISL706AEH, ISL706BEH and

ISL706CEH are contained in

also provided on our website for downloading.

Applications

• Supervisor for µ-Processors, µ-Controllers, FPGAs and DSPs

• Critical Power Supply Monitoring

• Reliable Replacement of Discrete Solutions

... As V rises, RST stays low. When V DD (ISL705AEH/BEH/CEH) or 3.08V (ISL706AEH/BEH/CEH) reset threshold, an internal timer releases RST after about 200ms. RST pulses low whenever V reset threshold brownout condition occurs in the middle of a previously initiated reset pulse, the pulse will continue for at least 140ms. On power-down, once V below the reset threshold, RST goes low and is guaranteed low until V 1 ...

... The ISL705CEH and ISL706CEH have open drain active low reset outputs (RST_OD). A pull-up resistor is needed to ensure RST_OD is high when V must be chosen in order not to exceed the sink capability of the RST_OD pin. The ISL705AEH has a sink capability of 3.2mA and the ISL706CEH has a sink capability of 1.2mA. Equation 4 may be used to select resistor R V ...
