Each input level is equivalent to LS-TTL. Therefore, the devices can be driven directly by LS-TTLs. Channels 1 and 2 are turned on or off at the same time. 102 ICs SI-3000KWM Series ■External Dimensions (TO252-5) 6.60 ±0.2 ±0.2 (Unit : mm) 6.60 5.34 ±0.2 ±0.2 1.10 C0 .60 2.30 ±0.2 5.34 (5.04) 0.50 ±0.1 ±0.20 (1.50) (5°) SEATING PLANE 0.00~0.127 ±0.3 MA X 6.10± p: ±0 .1 ±0.2 0D (4.41) 2.70 ±0.20 1.0 R0 .25 (0.80) (1.50) 9.90 ±0.2 MAX 0.70 0.50 1.27 TYP 1 2 3 4 1.27 TYP 5 2.70 (0.89) ±0.1 0~8 ° ±0.1 0.50 (1.00) 2.30 1.524 –0.127 +0.254 9.90 (5°) ±0.30 ■Block Diagram VIN 4 + φ CIN VC 1 – + (5°) ±0.2 (5°) (5°) Plastic Mold Package Type Flammability: UL 94V-0 Product Mass: Approx. 1.48 g Pin Assignment q VC w VO1 e GND r VIN t VO2 (5°) (5°) VOUT1 2 Drive REF OCP ON/ OFF + – + AMP2 – COUT1 + TSD VOUT2 5 Drive + + COUT2 OCP AMP2 – GND 3 ICs 103
