VN751PT PPAK Pinout

Notes

• Package: PPAK (5-pin power package with integrated heatspreader)
• OUTPUT pin: High-side driver; actively clamps inductive load transients to VCC − 47 to 57 V
• STATUS pin: Open-drain output; pulled low during overtemperature shutdown, overvoltage shutdown, or undervoltage condition; high impedance during normal operation
• INPUT pin: CMOS-compatible; logic low disables output, logic high enables output (subject to protection conditions)
• GND pin: Must be connected to load return and system ground; device includes protection against ground pin disconnection
• VCC pin: Supply voltage range 8–36 V; active clamp protects against low-energy spikes
• Protection features: Thermal shutdown (175 °C typical), current limiting (2.7–6.0 A), overvoltage shutdown (36 V), undervoltage shutdown (3–5.5 V), fast demagnetization of inductive loads

8 V < V CC < 36 V; -40 °C < T J < 125 °C; unless otherwise specified.
