Texas Instruments · Wireless Charge-Discharge ICs · VQFN-32(5x5)

BQ50002ARHBR from Texas Instruments, in a VQFN-32(5x5). 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 GND.
21 PGND power_in Power ground for the ground-referenced power stage; connect to GND.
22 PGND power_in Power ground for the ground-referenced power stage; connect to GND.
23 SW1 output Switch node of the half-bridge MOSFETs; 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).
