Pinout

Pin Name Type Function
1 VCC power_in Low-side supply voltage. Recommended operating range 10 V to 25 V (absolute max 25 V); typically 15 V. Referenced to VSS/COM.
2 HIN1 input High-side input for channel 1. Logic input in-phase with HO1. VIH ≥ 3.0 V, VIL ≤ 0.8 V, compatible with 3.3 V/5 V logic.
3 HIN2 input High-side input for channel 2. Logic input in-phase with HO2. VIH ≥ 3.0 V, VIL ≤ 0.8 V.
4 HIN3 input High-side input for channel 3. Logic input in-phase with HO3. VIH ≥ 3.0 V, VIL ≤ 0.8 V.
5 LIN1 input Low-side input for channel 1. Logic input in-phase with LO1. VIH ≥ 3.0 V, VIL ≤ 0.8 V.
6 LIN2 input Low-side input for channel 2. Logic input in-phase with LO2. VIH ≥ 3.0 V, VIL ≤ 0.8 V.
7 LIN3 input Low-side input for channel 3. Logic input in-phase with LO3. VIH ≥ 3.0 V, VIL ≤ 0.8 V.
8 FAULT output Active-low fault indicator (open-drain, RONFAULT 50-100 Ω). Asserts low on over-current (ITRIP) or low-side under-voltage lockout; released to high-Z after the RCIN fault-clear timer expires.
9 ITRIP input Over-current protection sense input. Threshold VITTH ≈ 0.50 V (hysteresis ≈ 0.09 V). Exceeding threshold shuts off all six outputs and asserts FAULT.
10 EN input Enable input. VTH+ ≤ 3.0 V asserts enable, VTH- ≥ 0.8 V disables. When low, all six outputs are forced low.
11 RCIN input External RC network sets the fault-clear delay (tFLTCLR ≈ 1.65 ms typ). Rising threshold VRCINTH ≈ 8 V, hysteresis ≈ 3 V, internal pull-down RONRCIN 50-100 Ω.
12 VSS power_in Logic/signal ground reference for the IC.
13 COM power_in Low-side gate driver common (power ground) return. All voltage limits are referenced to COM.
14 LO3 output Low-side gate drive output for channel 3. Referenced to COM; VOH ≈ VCC−0.8 V @ 25 mA, VOL ≈ 0.2 V @ 25 mA; source 200 mA / sink 350 mA.
15 LO2 output Low-side gate drive output for channel 2. Referenced to COM; source 200 mA / sink 350 mA typical.
16 LO1 output Low-side gate drive output for channel 1. Referenced to COM; source 200 mA / sink 350 mA typical.
17 NC unconnected No connection. Leave floating.
18 VS3 power_in High-side floating return (source of the external high-side MOSFET) for channel 3. Bootstrap capacitor connects between VB3 and VS3.
19 HO3 output High-side gate drive output for channel 3. Swings between VS3 and VB3; source 200 mA / sink 350 mA typical.
20 VB3 power_in High-side floating bootstrap supply for channel 3. Absolute max 650 V with respect to COM; VBS operating range referenced to VS3.
21 NC unconnected No connection. Leave floating.
22 VS2 power_in High-side floating return (source of the external high-side MOSFET) for channel 2. Bootstrap capacitor connects between VB2 and VS2.
23 HO2 output High-side gate drive output for channel 2. Swings between VS2 and VB2; source 200 mA / sink 350 mA typical.
24 VB2 power_in High-side floating bootstrap supply for channel 2. Absolute max 650 V with respect to COM.
25 NC unconnected No connection. Leave floating.
26 VS1 power_in High-side floating return (source of the external high-side MOSFET) for channel 1. Bootstrap capacitor connects between VB1 and VS1.
27 HO1 output High-side gate drive output for channel 1. Swings between VS1 and VB1; source 200 mA / sink 350 mA typical.
28 VB1 power_in High-side floating bootstrap supply for channel 1. Absolute max 650 V with respect to COM.
