Infineon 1ED3251MC12HXUMA1

The 1ED32xx family is a group of galvanically isolated single-channel driver ICs in a DSO-8 300 mil package. The driver ICs provide typical peak output currents up to 18 A. The family implements two-level slew rate control (2L-SRC). This feature allows for controlling two independent gate resistors, which enables the optimization of both EMI and switching losses. The family comprises standard output configuration and active Miller clamp output configurations with the same current rating to protect against parasitic turn-on. The input logic terminals operate safely with supply voltages of 3.3 V and 5 V. All input structures have threshold levels for support of 3.3 V microcontrollers. The driver IC family offers suitable output undervoltage lockout (UVLO) levels to operate various kinds of power transistors. The wide range of the output side supply voltage up to 40 V can be configured arbitrarily for positive and negative voltages as long as the absolute maximum of 40 V is not exceeded. All driver ICs have output sections with active shutdown.
