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).
