Features

common-emitter output transistor circuits. The uncommitted output transistors provide common-emitter output capability for each controller. The internal amplifiers exhibit a common-mode voltage range from 1.05 V to 1.45 V. The dead-time control comparator has no offset unless externally altered and may be used to provide 0% to 100% dead time. The on-chip oscillator may be operated by terminating RT (pin 2) and CT (pin 1). During low-VCC conditions, the undervoltage lockout control circuit feature inhibits the output until the internal circuitry is operational. The TL1453C is characterized for.
