www.DataSheet4U.com MAX707, MAX708 mP Supervisory Circuits The MAX707/708 are cost−effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required. The reset output is driven active within 20 msec of VCC falling through the reset voltage threshold. Reset is maintained with 200 mS of delay time after VCC rise above the reset threshold. The MAX707/708 have a low quiescent current of 12 mA at VCC = 3.3 V, an active−high RESET and active−low RESET with a push−pull output. The output is guaranteed valid down to VCC = 1.0 V. The MAX707/708 have a Manual Reset MR input and a +1.25 V threshold detector for power−fail input PFI. These devices are available in a Micro8 and SOIC−8 package.

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 MIL−STD−883, Method 3015. Machine Model Method 200 V. 2.
