The MP18831 is an isolated, dual-input half-bridge gate driver solution with up to 4A of source and sink peak current capacity. The gate driver is designed to drive power switching devices with a short propagation delay and pulse-width distortion.
By utilizing MPS's proprietary, capacitive-based isolation technology, the driver can provide up to 5kVRMS of withstand voltage (per UL1577) with a wide-body SOIC package. In addition, the common-mode transient immunity (CMTI) rating between the input side and output driver exceeds 100kV/μs. With these advanced features, the drivers provide high efficiency, high power density, and robustness to a wide variety of power applications.
The MP18831 integrates dual-input gate drivers in one package. Each output can be grounded to separate grounds or connected to a positive or negative voltage reference. The secondary topology can be configured as a half-bridge high-side/low-side driver that is controlled by two independent input signals. To prevent shoot-through in the half-bridge driver, the MP18831 provides a configurable dead time (DT) set by an external resistor.
The MP18831 is available in a narrow-body or wide-body SOIC-16 package (SOIC-16NB or SOIC-16WB, respectively), or an LGA-13 (5mmx5mm) package.
