6 I2C0 Addressing for I2C communication.

7 I2C1 Addressing for I2C communication.

8 SCL I2C clock.

9 SDA I2C data.

10 NC3 Reserved for test only. This pin should be grounded.

11 PM_OUT When Panel Mode is active, this pin will output a 400 kHz square wave signal with amplitude of 5V. Otherwise, it stays

low.

12 VDDA Analog supply voltage. This voltage is also used as the reference voltage. This pin should be connected to a 5V

supply, and bypassed to VSSA with a 1 µF and 0.1 µF monolithic ceramic capacitor.

13 VSSA Analog ground. The ground return for the analog supply and signals.

18 A4 A/D Input Channel 4. Connect a resistor divider to a 5V supply to set the maximum output current. Please refer to the

application section for more information on setting the resistor value.

19 AIIN Input current sensing pin.

20 A6 A/D Input Channel 6. Connect a resistor divider to a 5V supply to set the output voltage slew rate and various PM

configurations. Refer to configurable modes for SM72442 in the application section.

21 AIOUT Output current sensing pin.

22 I2C2 Addressing for I2C communication.

23 NC4 No Connect. This pin should be connected with 60.4k pull-up resistor to 5V.

24 LIB Low side boost PWM output.

25 HIB High side boost PWM output.

and associated test conditions, see the Electrical Characteristics tables.

(2) Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation

using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).

(3) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
