IRS2104 – 8-Lead PDIP Pinout

Notes

• Package: 8-Lead PDIP (DIP-8)
• Supply Pins: VCC (pin 8) and VB (pin 7) are the main supply inputs; VS (pin 5) and COM (pin 2) are the respective return paths
• Floating Channel: HO (pin 6) and VB/VS (pins 7/5) form the floating high-side driver, capable of operating up to 600 V offset
• Logic Inputs: IN (pin 3) and SD (pin 1) are logic-level inputs compatible with 3.3 V, 5 V, and 15 V logic
• Output Drivers: HO and LO feature high pulse current buffers (130 mA/270 mA typical) with cross-conduction prevention and internally set deadtime (~520 ns typical)

VBIAS (VCC, VBS) = 15 V, CL = 1000 pF and TA = 25 ° C unless otherwise specified.

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.

The i nput/ o utput logic timing diagram is shown in Fig. 1. For proper operation the device should be used within the recommended conditions. The VS offset rating is tested with all supplies biased at a 15 V differential.

Note 1: Logic operational for V S of -5 V to +600 V. Logic state held for V S of -5 V to -V BS . (Please refer to the Design Tip DT97-3 for more details).
