MAX707, MAX708 P Supervisory Circuits The MAX707/708 are costeffective system supervisor circuits designed to monitor V in digital systems and provide a reset signal CC to the host processor when necessary. No external components are required. The reset output is driven active within 20 sec of V falling CC MAX707, MAX708 V CC RESET MR RESET RESET GENERATOR V + CC V TH PFI + PFO 1.25 V GND Figure 1.

Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. This device series contains ESD protection and exceeds the following tests: Human Body Model 2000 V per MILSTD883, Method 3015. Machine Model Method 200 V. 2.
