About

EiceDRIVER™ 25 V single-channel low-side non-inverting gate driver IC

The 1ED44176N01F, 1ED44175N01B, and 1ED44173N01B are equipped with overcurrent protection (OCP) which is typically implemented by a current measurement with a comparator and multiple resistors and capacitors. The gate drivers provide cost and space savings by integrating the comparator. This family of low-side gate drivers utilizes Infineon’s proprietary latch immune CMOS technologies to enable a rugged monolithic construction while realizing best-in-class fault reporting accuracy with OCP threshold tolerance of ±5 percent. In addition, Infineon’s IC technology enables a tiny PG-SOT23 package (or DSO-8 for 1ED44176) by combining the fault output and enable functions into a single pin.

The family includes 1ED44171N01B, a cost-effective, simple driver with enable and fault reporting functions. It can also be used as a second source option to the popular IRS44273L with a single PCB layout. Enabling a single-supplier, dual sourcing strategy for fast-reacting supply flexibility.

Key features and system benefits

The 1ED4417x products integrate important protection features providing system benefits and improving reliablity.

The integrated overcurrent protection (OCP) feature  provides fast and accurate (+/-5%) sensing making the system design more reliable. For some parts, a single-pin is used for fault reporting and enable. The programmable fault clear time setup makes it easy to adjust to different microcontroller processing speeds. Under-voltage lock out (UVLO) protection is avaialbe for IGBTs and MOSFETs which eliminates swichting loss at low VCC supply voltages. A 25  VCC max supply voltage makes the IC more robus against VCC spikes in harsh circuit applications.  1ED44176 (DSO8) includes a separate logic and power ground pins to avoid noise coupling from output to input, improving noise immunity. 

The 1ED4417x family now includes 1ED44171N01B a dual sourcing option to Infineon's popular IRS44273L.

More about our low-side driver portfolio

With our state-of-the-art process, EiceDRIVER™ low-side gate driver ICs utilize low-voltage circuitry with the robust technology of high-voltage gate drivers. Our world-class fabrication techniques enable high-current gate drivers for high-power-density applications in industry-standard DSO-8 and small-form-factor SOT23 and WSON packages.

We offer comprehensive families of single-low-side and dual-low-side gate driver ICs with flexible options for output current, logic configurations, packages, and protection features such as undervoltage lockout (UVLO), integrated overcurrent protection (OCP), and truly differential inputs (TDI). We also offer automotive-qualified low-side gate driver ICs.
