BQ24005PWPR

Texas Instruments · Battery Management · HTSSOP-20-EP

BQ24005PWPR from Texas Instruments, in a HTSSOP-20-EP. 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 N/C unconnected No connect; this pin must be left floating.
2 IN power_in Input voltage that provides the charging voltage for the battery; recommended input voltage is 8.4 V to 10 V.
3 IN power_in Input voltage that provides the charging voltage for the battery; recommended input voltage is 8.4 V to 10 V.
4 VCC power_in Supply voltage; recommended VCC is 8.4 V to 10 V, with an absolute maximum of 13.5 V with respect to GND.
5 ISNS input Current sense input; an external sense resistor sets the magnitude of the charge current.
6 N/C unconnected No connect; this pin must be left floating.
7 APG/THERM input Adapter power-good input and thermistor sense input, with a falling-edge deglitch of 25 µs to 75 µs and an absolute maximum of 13.5 V with respect to GND.
8 EN input Active-high charge-enable input with internal pulldown; low level places the device in low-current standby mode.
9 VSEL input Charge-regulation selection input that selects 8.4 V/cell when high (minimum high-level input 2.25 V) and 8.2 V/cell when low (maximum low-level input 0.8 V).
10 GND/HEATSINK power_in Ground pin that must be connected to the PowerPAD heat-sink layout pattern.
11 N/C unconnected No connect; this pin must be left floating.
12 CR input Internal regulator bypass capacitor connection; CR output is 2.816 V to 2.88 V (2.85 V typical) at up to 100 µA load.
13 TMR SEL input Charge timer selection input with high-level input of 2.7 V minimum, low-level input of 0.6 V maximum, and absolute maximum of 13.5 V with respect to GND.
14 STAT1 output Status display output 1; output sink/source current is limited to 10 mA.
15 STAT2 output Status display output 2, present on bq24005 and bq24006 only; output sink/source current is limited to 10 mA.
16 AGND power_in Ground pin that must be connected close to the negative battery terminal.
17 VSENSE input Battery voltage sense input.
18 OUT power_out Charge current output; continuous output current is 1.2 A maximum and the absolute maximum output current is 2 A.
19 OUT power_out Charge current output; continuous output current is 1.2 A maximum and the absolute maximum output current is 2 A.
20 N/C unconnected No connect; this pin must be left floating.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: BQ24005PWPR
  • Footprint: Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm
  • 3D model: HTSSOP-20-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.2 mm nominal TSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: bq24005pwpr-etched.step / bq24005pwpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bq24005pwpr.step / bq24005pwpr.glb are the bare package body.
