Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | PWM1/CLK_IN | input | Input with a weak internal pull-down, controlled by bq500511A for system power delivery; acts as CLK_IN, where each rising edge steps the switching frequency (or duty factor) up or down. |+| 2 | PWM_CTRL | input | Input with a weak internal pull-down, controlled by bq500511A; with EN high, a HIGH level selects direct PWM control and a LOW level selects self-switching. |+| 3 | EN | input | Enable input with a weak internal pull-down; floating or pulling below 1.5 V disables the gate driver, demodulation and current sense, and pulling above 2.2 V enables the gate driver. |+| 4 | BP3 | output | LDO output regulating a 3-V supply; tie with a 2.2-µF capacitor to GND; for use by bq500511A only. |+| 5 | GND | power_in | Signal ground for the ground-referenced logic; all signal-level circuits should be referenced to this pin unless otherwise noted. |+| 6 | GND | power_in | Signal ground for the ground-referenced logic; all signal-level circuits should be referenced to this pin unless otherwise noted. |+| 7 | DMOUT2 | output | Demodulated 2-kHz signal output from CHAN2; for use by bq500511A only. |+| 8 | DMOUT1 | output | Demodulated 2-kHz signal output from CHAN1; for use by bq500511A only. |+| 9 | CLK_OUT | output | Internal oscillator clock output at 3.3-V logic level, with frequency equal to the current switching frequency and 50% duty factor. |+| 10 | MODE | input | Input with a weak internal pull-down; floating or pulling below 1.5 V selects frequency control, and pulling above 2.2 V selects pulse-width control of the internal PWM signal. |+| 11 | DMIN1 | input | Modulated signal input from the coil for demodulation channel 1; recommended range is -0.3 V to 5 V and absolute maximum range is -5 V to 7 V. |+| 12 | DMIN2 | input | Modulated signal input from the coil for demodulation channel 2; recommended range is -0.3 V to 5 V and absolute maximum is 7 V. |+| 13 | GND | power_in | Signal ground for the ground-referenced logic; all signal-level circuits should be referenced to this pin unless otherwise noted. |+| 14 | PVIN2 | power_in | DC input voltage for the half-bridge MOSFET, recommended 4.5 V to 5.5 V with absolute maximum of 7 V; bypass to GND as specified in the datasheet. |+| 15 | PVIN2 | power_in | DC input voltage for the half-bridge MOSFET, recommended 4.5 V to 5.5 V with absolute maximum of 7 V; bypass to GND as specified in the datasheet. |+| 16 | BOOT2 | bidirectional | Positive supply rail for the high-side gate driver; connect a 0.1-µF ceramic capacitor between BOOT2 and SW2; absolute maximum is 14 V relative to GND. |+| 17 | SW2 | output | Switch node of the half-bridge MOSFETs; connect to the resonant capacitor. |+| 18 | SW2 | output | Switch node of the half-bridge MOSFETs; connect to the resonant capacitor. |+| 19 | SW2 | output | Switch node of the half-bridge MOSFETs; connect to the resonant capacitor. |+| 20 | PGND | power_in | Power ground for the ground-referenced power stage;

connect to the TX coil. |+| 24 | SW1 | output | Switch node of the half-bridge MOSFETs; connect to the TX coil. |+| 25 | BOOT1 | bidirectional | Positive supply rail for the high-side gate driver; connect a 0.1-µF ceramic capacitor between BOOT1 and SW1; absolute maximum is 14 V relative to GND. |+| 26 | SW1 | output | Switch node of the half-bridge MOSFETs; connect to the TX coil. |+| 27 | PVIN1 | power_in | DC input voltage for the half-bridge MOSFET, recommended 4.5 V to 5.5 V with absolute maximum of 7 V; bypass to GND as specified in the datasheet. |+| 28 | PVIN1 | power_in | DC input voltage for the half-bridge MOSFET, recommended 4.5 V to 5.5 V with absolute maximum of 7 V; bypass to GND as specified in the datasheet. |+| 29 | CSN | input | Current sense amplifier negative input; CSN to CSP differential is limited to -0.5 V to 0.5 V. |+| 30 | CSP | input | Current sense amplifier positive input; connect the current sense resistor as close as possible to this pin, which also serves as the quiet node for the power supply input. |+| 31 | CSO | output | Current sense amplifier output with voltage gain of 50; for use by bq500511A only. |+| 32 | PWM2/UP_DN | input | Input with a weak internal pull-down, controlled by bq500511A; sets the direction of self-switching frequency steps (LOW increases frequency, HIGH decreases it when PWM_CTRL is LOW and MODE is LOW). |+| 33 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-32(5x5) |+| Category | Power Management (PMIC) |+| Pins | 33 |++## CAD (KiCad official)++- Symbol: `BQ50002ARHBR`+- Footprint: `Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.3x3.3mm`+- 3D model: VQFN-32(5x5) (KiCad packages3D, STEP)+- 3D model files: `bq50002arhbr-etched.step` / `bq50002arhbr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready);
