APPLICATIO HI TS

The logic and ground pins function as a differential logic

input with a common-mode range of V_CCto V_CC– 20V and

a differential threshold voltage (V_LOGIC– GND) of 1.5V.

Note that if either Logic In or GND are left open the switch

remains inactive.

Care must be exercised when operating near the

maximumswitchvoltage.Ahighcurrentorcapacitiveload

may trip the current limit circuit at turn-on, thereby

adversely affecting the risetime of V_OUT. The risetime is

then governed by the current limit divided by the load

capacitance, while the falltime is a function of the complex

load. In addition, at switch voltages greater than 18V

the switch current must be less than 0.5A or the device

output will not pull up. Check the short circuit current

characteristics for more detailed information.

The LT1089 must be protected against overvoltage at

turn-offwhendrivinginductiveloads.Theinductiveflyback

voltage can easily exceed the maximum operating switch

voltage (V_CC– V_OUT) of 20V, potentially damaging the

switch. The solution is to clamp the switch voltage to 20V

or less with a zener diode. Remember that the switch can

handle 7.5A and the Zener may be required to handle the

same amount of current.
