HT33153ARZ from HTCSEMI, in a SOP-8. 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	Current Sense Input	input	Current sense input for overcurrent and short-circuit comparators. Overcurrent threshold typ 65 mV, short-circuit threshold typ 130 mV (when Vpin8 > 7.0 V). Input current typ -1.4 uA at Vsi = 0 V.
2	Kelvin Gnd	power_in	Kelvin ground reference for the current-sense comparators. Must always be between VEE and VCC; typically connected to VEE. Rated -0.3 V to VCC absolute maximum.
3	VEE	power_in	Negative supply / gate-driver return rail. Combined with VCC gives the total supply voltage (VCC-VEE max 20 V). Provides negative gate-drive capability.
4	Input	input	Inverting logic input controlling the drive output. VIH typ 2.70 V (max 3.2 V), VIL typ 2.30 V (min 1.2 V). Input current typ 130 uA at VIH=3.0 V.
5	Drive Output	output	Gate drive output stage. 1.0 A source / 2.0 A sink capability, VOH typ 13.9 V at Isource=500 mA, VOL typ 2.0 V at Isink=1.0 A. Internal ~100 kOhm pull-down resistor to VEE.
6	VCC	power_in	Positive supply rail for the driver. VCC-VEE max 20 V. UVLO startup typ 12 V, disable typ 11 V. Standby ICC typ 7.2 mA, operating typ 7.9 mA (CL=1 nF, f=20 kHz).
7	Fault Output	output	Open fault indication output driven by short-circuit and overcurrent latches. VFH typ 13.3 V at Isource=20 mA, VFL typ 0.2 V at Isink=5.0 mA. Source current max 25 mA, sink 10 mA.
8	Fault Blanking/Desaturation Input	input	Programmable fault blanking / desaturation sense input. Threshold typ 6.5 V (min 6.0, max 7.0). Internal charge current typ -270 uA (200-300 uA); discharge current typ 2.5 mA (min 1.0). Rated -0.3 V to VCC absolute maximum.
