| Reference | Value | Description |
|---|---|---|
| Q5 | AO3401A | -4.0A Id, -30V Vds, P-Channel MOSFET, SOT-23 |
| U1 | TPS651851 | EPD PMIC, 48-VQFN RSL0048G 6x6 0.4mm. VPOS/VNEG LDO 200 mA, CP1/CP2 15 mA, DCDC1 ILIMIT 2.5 A. I2C address 0x68 (NOT 0x48). Pinout is NOT compatible with TPS65186 - 18 pins differ. |
| U2 | TPS7A2533 | 3.3 V fixed-output 300 mA LDO, WSON-6 (DRV). TPS7A25 family - pin-identical to the TPS7A26 (OUT/NC/PG/EN/GND/IN), same 18 V input and 2 uA Iq, 300 mA instead of 500 mA. Chosen for U2 because the 18 V rating is real protection on a rail fed straight from USB VBUS. |
| U4 | SN74AVC16T245 | 16-bit dual-supply bus transceiver, 3-state, AVC family. VCCA and VCCB independently 1.2-3.6 V - A port + control pins on VCCA, B port on VCCB. Ioff partial-power-down and VCC isolation (either rail at GND puts both ports Hi-Z). 200 Mbps level-shifting to 1.8 V. Bus and GND pins match SN74AUC16244/SN74AVC16244 pin-for-pin; pins 1/24 are DIR not ~{OE}, and the four VCC pins split 7+18=VCCB, 31+42=VCCA. TSSOP-48 (DGG) |
| U5 | LP5912-1.8 | 1.8 V fixed-output 500 mA low-noise LDO, WSON-6 (DRV). 12 uVrms vs the TPS7A26 300 uVrms. Pin-identical to TPS7A2633DRVR. WARNING input is 6.5 V recommended / 7 V absolute max - safe on the regulated +3V3_EPD feeding U5, NOT safe on a rail fed directly from USB VBUS. |
