Phone fast chargers, electric vehicles, brushless motors and portable storage have raised demand for low- and mid-voltage MOSFETs. SGT devices are the usual choice in fast charge, motor drives and power management.
The MHCHXM SGT family uses a shielded-gate trench. The cell and the trench are arranged so specific on-resistance Rsp (Rds(on) times die area) comes down. In a dense package such as PDFN or TO-263M, the same outline then delivers more power. The shield also cuts Qg and Qrr, so turn-off loss and current spikes are smaller and the system is steadier. The input-capacitance ratio is set so Miller coupling is less likely to pull the gate through, which lowers shoot-through risk.
Characteristics
- Low Rsp, so power density is higher
- Low FOM (Rds(on) × Qg), so switching loss is lower
- Low Qrr, so turn-off loss is lower
- Low Irrm, so turn-off voltage stress is lower
- More avalanche and surge headroom
