STSPIN233

STMicroelectronics · Gate Drivers · QFN-16-EP(3x3)

STSPIN233 from STMicroelectronics, in a QFN-16-EP(3x3). 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	INU	input	Logic input driving the U half-bridge output state (5V max logic input, VIH min 1.6V / VIL max 0.6V per Table 5).
2	ENU	input	Logic input enabling the U half-bridge output; when low the U output is forced high impedance (per Table 8 truth table).
3	OUTU	output	Power bridge output U, driving the motor phase U with continuous output current rating up to 1.3 Arms.
4	SENSEU	passive	Sense output of bridge U for three-shunt current sensing; sense pin voltage range is -1 V to 1 V per absolute maximum ratings.
5	VS	power_in	Device supply voltage input; recommended operating range 1.8 V to 10 V (absolute maximum -0.3 V to 11 V).
6	GND	power_in	Device ground reference pin.
7	OUTV	output	Power bridge output V, driving the motor phase V with continuous output current rating up to 1.3 Arms.
8	SENSEV	passive	Sense output of bridge V for three-shunt current sensing; sense pin voltage range is -1 V to 1 V per absolute maximum ratings.
9	SENSEW	passive	Sense output of bridge W for three-shunt current sensing; sense pin voltage range is -1 V to 1 V per absolute maximum ratings.
10	OUTW	output	Power bridge output W, driving the motor phase W with continuous output current rating up to 1.3 Arms.
11	INW	input	Logic input driving the W half-bridge output state.
12	ENW	input	Logic input enabling the W half-bridge output; when low the W output is forced high impedance.
13	EN\FAULT	bidirectional	5V-compliant logic input and open-drain output; when driven low it disables the power stage, and it is internally forced low through an open-drain MOSFET when an overcurrent, short-circuit, or thermal-shutdown fault occurs.
14	STBY\RESET	input	5V-compliant logic input; forcing it below VSTBYL (max 0.9 V) places the device in low-consumption standby mode, cutting supply to control circuitry, while VSTBYH (min 1.48 V) exits standby.
15	INV	input	Logic input driving the V half-bridge output state.
16	ENV	input	Logic input enabling the V half-bridge output; when low the V output is forced high impedance.
17	EPAD	power_in	Exposed pad on the package underside; per the pin connection note it must be connected to ground for proper thermal and electrical operation.
