TQFP Pin Configuration Table 2. Pin Function Descriptions Pin No. LFCSP TQFP Mnemonic Description 15-20 1, 12–13, 18–25, 36–37, 48 NC No connection. 1–5 2–6 VX1–5 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. 6–9 7–10 VP1–4 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, 1.25 V to 3.00 V, and 0.573 V to 1.375 V. 10 11 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 2.5 V to 6.0 V. 11 14 AGND Ground Return for Input Attenuators. 12 15 REFGND Ground Return for On-Chip Reference Circuits. 13 16 REFIN Reference Input for ADC. Nominally, 2.048 V. 14 17 REFOUT 2.048 V Reference Output. 21–30 26–35 PDO10–1 Programmable Output Drivers. 31 38 PDOGND Ground Return for Output Drivers. 32 39 VCCP Central Charge-Pump Voltage of 5.25 V. A reservoir capacitor must be connected between this pin and GND. 33 40 A0 Logic Input. This pin sets the seventh bit of the SMBus interface address. 34 41 A1 Logic Input. This pin sets the sixth bit of the SMBus interface address. 35 42 SCL SMBus Clock Pin. Open-drain output requires external resistive pull-up. 36 43 SDA SMBus Data I/O Pin. Open-drain output requires external resistive pull-up. 37 44 AUX2 Auxiliary, Single-Ended ADC Input. 38 45 AUX1 Auxiliary, Single-Ended ADC Input. 39 46 VDDCAP Device Supply Voltage. Linearly regulated from the highest of the VP1–4, VH pins to a typical of 4.75 V. 40 47 GND Supply Ground. |
