概要

概要

The device is a high voltage half bridge driver with built in oscillator. The frequency of the oscillator can be programmed using external resistor and capacitor. The internal circuitry of the device allows it to be driven also by external logic signal.

The output drivers are designed to drive external n-channel power MOSFET and IGBT. The internal logic assures a dead time to avoid cross-conduction of the power devices.

Two version are available: L6571A and L6571B. They differ in the internal dead time: 1.25µs and 0.72µs (typ.)

  • 特徴

    • ESD PROTECTION
    • dV/dt IMMUNITY UP TO ±50V/ns
    • PROGRAMMABLE OSCILLATOR FREQUENCY
    • UNDER VOLTAGE LOCKOUT WITH HYSTERESIS
    • HIGH VOLTAGE RAIL UP TO 600V
    • 15.6V ZENER CLAMP ON VS
    • BCD OFF LINE TECHNOLOGY
    • VERY LOW START UP CURRENT: 150µA
    • DEAD TIME 1.25µs (L6571A) or 0.72µs (L6571B)
    • DRIVER CURRENT CAPABILITY: SINK CURRENT = 270mASOURCE CURRENT = 170mA\t
