Pin Descriptions (continued)

Pin

Name

Description

22

NC8

No Connect. This pin should be grounded using a 10k resistor.

23

NC9

No Connect. This pin should be connected with 150k pull-up resistor to 5V supply.

24

LIB

Low side boost PWM output.

25

HIB

High side boost PWM output.

26

HIA

High side buck PWM output.

27

LIA

Low side buck PWM output.

28

OVP

Overvoltage Protection Pin. Active Low. SM72441 will reset once voltage on this pin drops below its threshold voltage.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is ensured. Operating Ratings indicate conditions for which the device is intended to be functional, but

does not ensure specific performance limits. For specified performance limits and associated test conditions, see the Electrical

Characteristics tables.

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

(3)

The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin.
