4 / 15 page SM72441 SNOSB64G – OCTOBER 2010 – REVISED APRIL 2013 www.ti.com 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. Absolute Maximum Ratings (1) (2) Analog Supply Voltage VA (VDDA -VSSA) -0.3 to 6.0V Analog Supply Voltage VD (VDDD -VSSD) -0.3 to VA +0.3V, max 6.0V Voltage on Any Pin to GND -0.3 to VA +0.3V Input Current at Any Pin (Note 3) ±10 mA Package Input Current (Note 3) ±20 mA Storage Temperature Range -65°C to +150°C ESD Rating(3) Human Body Model 2 kV (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. (2) 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. Recommended Operating Conditions Operating Temperature -40°C to 105°C VA Supply Voltage +4.75V to +5.25V VD Supply Voltage +4.75V to VA Digital Input Voltage 0 to VA Analog Input Voltage 0 to VA Junction Temperature -40°C to 125°C 4 Submit Documentation Feedback Copyright © 2010–2013, Texas Instruments Incorporated Product Folder Links: SM72441 |
