SS6810H

LEADPOWER · Motor Driver ICs · ETSSOP-20

SS6810H from LEADPOWER, in a ETSSOP-20. 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	GND	power_in	Ground.
2	OUT1B	output	Channel 1 H-bridge output B, rated 1.0 A/phase DC recommended (1.5 A absolute max).
3	RNF1	passive	Channel 1 current-sense resistor connection; absolute max voltage 0.7 V, chopping current ICHOP = VREF/(5×RRNF).
4	OUT1A	output	Channel 1 H-bridge output A, rated 1.0 A/phase DC recommended (1.5 A absolute max).
5	VCC1	power_in	Channel 1 H-bridge supply, 10 V to 32 V recommended (38 V absolute max).
6	CR	bidirectional	Internal clock setting pin for external RC setting the PWM chopping period and minimum on-time (C=1000 pF, R=91 kΩ typical; C 470-1500 pF, R ≥15 kΩ).
7	MTH	input	Current decay mode selection: 0-0.3 V slow, 0.4-1.0 V mixed, 1.5-3.5 V fast decay.
8	VREF	power_in	H-bridge output current setting reference input, 0 V to 3.0 V.
9	PS	input	Sleep mode input; low gives standby with outputs High-Z, high enables operation (logic high ≥2.0 V, low ≤0.8 V, internal pull-down).
10	PHASE1	input	Channel 1 output direction control (high ≥2.8 V, low ≤0.6 V, internal pull-down).
11	PHASE2	input	Channel 2 output direction control (high ≥2.8 V, low ≤0.6 V, internal pull-down).
12	I01	input	Channel 1 current setting input bit 0 (high ≥2.0 V, low ≤0.8 V, internal pull-down).
13	I11	input	Channel 1 current setting input bit 1 (high ≥2.0 V, low ≤0.8 V, internal pull-down).
14	I02	input	Channel 2 current setting input bit 0 (high ≥2.0 V, low ≤0.8 V, internal pull-down).
15	I12	input	Channel 2 current setting input bit 1 (high ≥2.0 V, low ≤0.8 V, internal pull-down).
16	GND	power_in	Ground.
17	VCC2	power_in	Channel 2 H-bridge supply, 10 V to 32 V recommended (38 V absolute max).
18	OUT2A	output	Channel 2 H-bridge output A, rated 1.0 A/phase DC recommended (1.5 A absolute max).
19	RNF2	passive	Channel 2 current-sense resistor connection; absolute max voltage 0.7 V, chopping current ICHOP = VREF/(5×RRNF).
20	OUT2B	output	Channel 2 H-bridge output B, rated 1.0 A/phase DC recommended (1.5 A absolute max).
21	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
