IF POSSIBLE, THIS PAD SHOULD BE SOLDERED TO THE BOARD FOR IMPROVED MECHANICAL STABILITY. Figure 3. LQFP Pin Configuration Figure 4. LFCSP Pin Configuration Table 4. Pin Function Descriptions Pin No. Mnemonic LQFP LFCSP1 Description 1, 6, 15, 16, 21, 22, 37, 38 NC No Connect. 1 to 4 2 to 5 VX1 to VX4 (VXx) High Impedance Inputs to Supply Fault Detectors. Fault thresholds can be set from 0.573 V to 1.375 V. Alternatively, these pins can be used as general-purpose digital inputs. 5 to 7 7 to 9 VP1 to VP3 (VPx) Low Voltage Inputs to Supply Fault Detectors. Three input ranges can be set by altering the input attenuation on a potential divider connected to these pins, the output of which connects to a supply fault detector. These pins allow thresholds from 2.5 V to 6.0 V, from 1.25 V to 3.00 V, and from 0.573 V to 1.375 V. 8 10 VH High Voltage Input to Supply Fault Detectors. Three input ranges can be set by altering the input attenuation on a potential divider connected to this pin, the output of which connects to a supply fault detector. This pin allows thresholds from 6.0 V to 14.4 V and from 2.5 V to 6.0 V. 9 11 AGND2 Ground Return for Input Attenuators. 10 12 REFGND2 Ground Return for On-Chip Reference Circuits. 11 13 REFIN Reference Input for ADC. Nominally, 2.048 V. This pin must be driven by a reference voltage. The on-board reference can be used by connecting the REFOUT pin to the REFIN pin. This is the normal configuration. 12 14 REFOUT 2.048 V Reference Output. A reservoir capacitor must be connected between this pin and GND. A 10 μF capacitor is recommended for this purpose. 13 to 16 17 to 20 DAC1 to DAC4 Voltage Output DACs. These pins default to high impedance at power-up. 17 to 24 23 to 30 PDO8 to PDO1 Programmable Output Drivers. 25 31 PDOGND2 Ground Return for Output Drivers. 26 32 VCCP Central Charge-Pump Voltage of 5.25 V. A reservoir capacitor must be connected between this pin and GND. A 10 μF capacitor is recommended for this purpose. 27 33 A0 Logic Input. This pin sets the seventh bit of the SMBus interface address. 28 34 A1 Logic Input. This pin sets the sixth bit of the SMBus interface address. 29 35 SCL SMBus Clock Pin. Bidirectional open drain requires external resistive pull-up. 30 36 SDA SMBus Data Pin. Bidirectional open drain requires external resistive pull-up. |
