The floating high-side driver can work with rail voltages up to 100 V. The single control input is compatible with TTL signal levels and a single external resistor programs the switching transition dead-time through tightly matched turnon delay circuits. The robust level shift technology operates at high speed while consuming low power and provides clean output transitions. Undervoltage lockout (UVLO) disables the gate driver when either the low side or the bootstrapped high-side sup...
