MAX4824 Maxim, MAX4824 Datasheet - Page 4

• Manufacturer Part Number: MAX4824
• Description: The MAX4822–MAX4825 8-channel relay drivers offer built-in kickback protection and drive +3V/+5V nonlatching or dual-coil-latching relays
• Manufacturer: Maxim

+3.3V/+5V, 8-Channel Relay Drivers with Fast
Recovery Time and Power-Save Mode
ELECTRICAL CHARACTERISTICS (continued)

noted.) (Note 1)
4
Note 1: Specifications at -40°C are guaranteed by design and not production tested.
Note 2: Thermal shutdown disables power save from all channels to reduce power dissipation inside the device.
Note 3: Thermal shutdown turns off all channels.
Note 4: The circuit can set the output voltage in power-save mode only if I
Note 5: After relay turn-off, inductive kickback can momentarily cause the OUT_ voltage to exceed V
Note 6: Guaranteed by design.
Note 7: For other capacitance values, use the equation t
