TS391IQ2T

STMicroelectronics · Comparators · QFN-8L

TS391IQ2T from STMicroelectronics, in a QFN-8L. 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	NC	unconnected	Drawn as a dashed pad with no label or internal connection in the DFN8 2x2 pin diagram.
2	E+	input	Non-inverting comparator input; common-mode range is 0 to (VCC+) - 1.5 V at 25 °C and may not go below -0.3 V.
3	E-	input	Inverting comparator input; common-mode range is 0 to (VCC+) - 1.5 V at 25 °C and may not go below -0.3 V.
4	VCC-	power_in	Negative supply, or ground in single-supply operation; supply is 2 to 36 V or ±1 to ±18 V.
5	NC	unconnected	Drawn as a dashed pad with no label or internal connection in the DFN8 2x2 pin diagram.
6	Out	output	Open-collector comparator output, which can be pulled up to 36 V even if VCC is lower, with a typical sink of 6 to 16 mA and a short-circuit current of about 20 mA.
7	VCC+	power_in	Positive supply; supply is 2 to 36 V or ±1 to ±18 V, with a typical supply current of 0.2 mA at 5 V.
8	NC	unconnected	Drawn as a dashed pad with no label or internal connection in the DFN8 2x2 pin diagram.
9	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

Symbol: TS391IQ2T
Footprint: Package_DFN_QFN:QFN-8-1EP_6x5mm_P1.27mm_EP3.4x4.2mm
3D model: QFN-8L, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN 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: ts391iq2t-etched.step / ts391iq2t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ts391iq2t.step / ts391iq2t.glb are the bare package body.
