GC1267F

SX-globalchip · Brushed DC Motor Drivers · SSOP-16

GC1267F from SX-globalchip, in a SSOP-16. 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	OUT2P	output	High side output 2 of the single-phase full-wave bridge.
2	OUT2N	output	Low side output 2 of the single-phase full-wave bridge.
3	Vcc	power_in	Power supply pin; use a stabilization capacitor of 1µF or more on the signal side and connect VCC and GND with a thick, shortest pattern.
4	SENSE	bidirectional	Current limiting detection pin; when its voltage exceeds 0.2V the current is limited and operation enters lower regeneration mode, and it must be connected to GND when not used.
5	RMI	input	Minimum speed setting pin with a 0 to 5 V input range; pull up to 5VREG when not used, and insert a current limiting resistor if driven from an external supply.
6	VTH	input	Speed control pin with a 0 to 5 V input range; connect to GND for full speed when not used, and use 20kHz to 100kHz pulse input (20kHz to 50kHz recommended) with a current limiting resistor.
7	CPWM	bidirectional	Pin for the capacitor that sets the PWM basic frequency, where CP = 220pF gives 30kHz; the capacitor must be connected even when speed control is not used.
8	FG	output	Rotation speed detection open collector output that follows the phase changeover; keep open when not used, with a withstand voltage of 19 V and maximum output current of 10 mA.
9	IN-	input	Negative Hall signal input with differential sensitivity of ±10 to ±20 mV including offset and hysteresis.
10	IN+	input	Positive Hall signal input with a common-phase input voltage range of 0.2 to 3 V.
11	CT	bidirectional	Lock detection capacitor pin where locking occurs at 3.0V and unlocking at 1.1V; connect to GND when locking is not used.
12	S-S	bidirectional	Soft-start setting capacitor pin connected between 5VREG and S-S with a recommended capacitor of 0.1µF to 1µF; connect to GND when not used.
13	5VREG	bidirectional	Internal 5V reference output, 4.80 to 5.10 V at 5 mA, with a maximum output current of 20 mA.
14	SGND	power_in	Ground pin connected to the control circuit power supply system.
15	OUT1N	output	Low side output 1 of the single-phase full-wave bridge.
16	OUT1P	output	High side output 1 of the single-phase full-wave bridge.
