The MPQ18831 is an isolated half-bridge gate driver solution with up to a 4A source and 8A 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 isolation voltage (per UL 1577) with a wide-body SOIC package. In addition, the common-mode transient immunity (CMTI) between the input side and output driver exceeds 150kV/μs. With these advanced features, the drivers operate with high efficiency, high power density, and robustness across a wide variety of automotive power applications.
The MPQ18831 integrates dual-channel 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 (HS) or low-side (LS) driver that is controlled by two independent input signals. To prevent shoot-through in the half-bridge driver, the MPQ18831 provides a configurable dead time (DT) set by an external resistor.
A wide primary-side VDDI supply range makes the driver well-suited to be interfaced with 3.3V or 5V digital controllers. The secondary-side driver accepts up to 30V supply, and all of the supply voltage pins feature various under-voltage lockout (UVLO) protections.
The MP18831 is available in a narrow-body or wide-body SOIC-16 package (SOIC-16 NB or SOIC-16 WB, respectively), an SOIC16-14 (3mm creepage) package, or an LGA-13 (5mmx5mm) package.
