Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDDCP | power_out | Charge pump output. Connect a capacitor (typ 470 nF) to BAT. Do not load this pin. Charge pump voltage V(VDDCP)-V(BAT) is typically 12 V (9 V-14 V). |+| 2 | BAT | power_in | Top of battery stack. Battery cell input supply pin; recommended operating range 8 V to 75 V (100 V absolute max). |+| 3 | NC | unconnected | No connect. Leave the pin floating. |+| 4 | CHG_EN | input | Charge FET enable. Digital input from AFE or MCU (VIL max 0.6 V, VIH min 1.2 V, 15 V absolute max). Internal ~1 MΩ pull-down. Must be current limited (max 5 mA). |+| 5 | CP_EN | input | Charge pump enable. Internally logic-ORed with CHG_EN and DSG_EN signals. Digital input (VIL max 0.6 V, VIH min 1.2 V, 15 V absolute max) with internal ~1 MΩ pull-down. |+| 6 | DSG_EN | input | Discharge FET enable. Digital input (VIL max 0.6 V, VIH min 1.2 V, 15 V absolute max) with internal ~1 MΩ pull-down. |+| 7 | PMON_EN | input | Pack monitor enable. Enables the internal switch (typ 2.5 kΩ, 1.5-3.5 kΩ) between PACK and PACKDIV pins to allow pack-voltage sensing. Recommended to tie to ground if unused. |+| 8 | PCHG_EN | input | Precharge FET enable. Digital input controlling the P-channel precharge FET driver. Recommended to tie to ground if unused. |+| 9 | VSS | power_in | Ground reference. |+| 10 | PACKDIV | output | PACK voltage after internal switch. Connect to MCU ADC via an external resistor divider to sense the pack voltage when PMON_EN is high. Leave floating if unused. |+| 11 | PACK | power_in | Analog input from the PACK+ terminal. Charger/load voltage input; recommended range 0 V to 75 V (100 V absolute max). |+| 12 | DSG | output | Gate drive for discharge N-channel high-side FET. Gate drive voltage V(DSG)-V(PACK) typically 12 V (9-14 V) when DSG_EN=Hi. Driver on-resistance 3.5 kΩ typ; off-resistance 1 kΩ typ. |+| 13 | NC | unconnected | No connect. Leave the pin floating. |+| 14 | PCHG | output | Gate drive for precharge P-channel FET. Provides current-limited pre-charge of significantly depleted cell packs. Gate drive V(PACK)-V(PCHG) typically 12 V (5-14 V) when V(PACK)>17 V and V(BAT)<V(PACK). Leave floating if unused. |+| 15 | NC | unconnected | No connect. Leave the pin floating. |+| 16 | CHG | output | Gate drive for charge N-channel high-side FET. Gate drive voltage V(CHG)-V(BAT) typically 12 V (9-14 V) when CHG_EN=Hi. Driver on-resistance 1.1 kΩ typ; off-resistance 0.3 kΩ typ. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | PMIC |+| Pins | 16 |++## Ordering variants++- `BQ76200PWR`++## CAD (KiCad official)++- Symbol: `BQ76200PWR`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/bq76200.pdf) (30 pp, sha256 `fb2ebcf8e875aa0a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
