TULI Design Brief Analysis

Thought for 1 min 48 sec

Ringkas progres saat ini (berdasarkan skematik proyek yang ada):

Instans “kanonik” sudah ADA di skematik:
- Boost 5 V: U8 (TPS61230)
- MCU ESP32: U4
- LED driver: U14 (AL8805)
- LoRa: U5 (RFM95W)
- Charger: U3 (BQ24074)
- Komparator: U6 (LMV331)
- Mic preamp: IC1 (MAX9814)
- MOSFET buzzer: Q1 (AO3400A)
Bagian “baru” yang Anda minta sebagian besar SUDAH ADA:
- Jaringan FB boost: R121 (681 kΩ), R122 (75 kΩ), C122 (22 pF) sudah ada (belum terhubung).
- LED CTRL path: R_LED_PWM (100 Ω 0603) dan R_CTRL_PD (100 kΩ 0603) sudah ada (belum dipasang ke pin CTRL U14).
- Pull‑up NSS: R_NSS_PULLUP (10 kΩ 0603) sudah ada.
- BYPASS MAX9814: Cbypass (0.1 µF 0603) sudah ada.
- Resistor charger: R_ISET (1.78 kΩ 0603 1%), R_ILIM (1.30 kΩ 0603 1%), R_ITERM (3.01 kΩ 0603 1%) sudah ada.
- Sense LED 0.28 Ω: RS_LED_SENSE sudah ada.
- Gate pulldown MOSFET: RGATE_PD sudah ada.
- Buzzer aktif: BZ1 BELUM ada.
Catatan konflik/duplikasi designator yang memang ada di skematik Anda saat ini (belum diubah):
- R21 dan R22 muncul lebih dari sekali dengan nilai berbeda, serta ada C22 ganda. Karena itu, kita sudah alihkan FB boost ke R121/R122/C122 untuk menghindari overwrite.
Status NET (koneksi): belum ada net bernama di proyek (“No nets have been defined yet”).
- Artinya: +5V_BOOST, +3V3, LED_PWM series, NSS pull‑up, BYPASS, ISET/ILIM/ITERM, sense LED, dan buzzer low‑side BELUM terhubung. Juga U14:VIN belum dikaitkan ke +5V_BOOST (dan tidak terikat ke +3V3).
Remap pin yang sudah teridentifikasi untuk wiring berikutnya:
- AL8805: pin “CS/SET” pada simbol adalah U14:SET (dipakai sebagai pin sense arus). CTRL tetap U14:CTRL.
- MAX9814: pin BYPASS pada simbol tercantum sebagai CT (IC1:CT).

Ringkas to‑do agar sesuai brief Anda:

Tambah BZ1, lalu wire buzzer low‑side ke Q1 (Gate=pin1 via R27/RGATE_PD, Source=pin2→GND, Drain=pin3→BZ1−; BZ1+→+5V_BOOST).
Buat net +5V_BOOST dan +3V3; hubungkan:
- +5V_BOOST: U8:VOUT (pin3/4) → U14:VIN.
- +3V3: U4:3V3, U5:3.3V, U6:VCC, U3:EN2, R_NSS_PULLUP (10 kΩ 0603):P?, R25:?, R23:?.
Wire jaringan FB U8: U8:FB ↔ R121/R122/C122 sesuai matriks (tanpa menyinggung pin PG).
LED CTRL seri: U4:IO32 → R_LED_PWM (100 Ω 0603) → U14:CTRL; R_CTRL_PD (100 kΩ 0603) ke GND.
NSS pull‑up: SPI_NSS ↔ R_NSS_PULLUP (10 kΩ 0603) ↔ +3V3.
MAX9814 BYPASS: IC1:CT ↔ Cbypass (0.1 µF 0603) ↔ GND.
BQ24074 ISET/ILIM/ITERM dan mode: U3:ISET/ILIM/ITERM ↔ resistor ke GND; EN2→+3V3; EN1/CE→GND.

Jika Anda setuju, saya bisa jalankan langkah wiring di atas sekarang dalam satu pass dan kembalikan checklist verifikasinya.

Got it. I’ll execute the plan to add BZ1, create +5V_BOOST/+3V3, and wire all specified connections to U8/U4/U14/U5/U3/U6/IC1/Q1.

I’ll report:
