MP18831 Isolated, Dual-Input Control, High-Side/Low-Side Half-Bridge Gate Driver
The MP18831 is an isolated, half-bridge gate driver solution with up to 4A of source and sink peak current capability. The gate driver is designed to drive power switching devices with a short propagation delay and minimal pulse-width distortion. By utilizing MPS's proprietary capacitive-based isolation technology, the driver can provide up to 5kVRMS withstand voltage (per UL 1577) (SOIC wide-body package option). It can also provide a common-mode transient immunity (CMTI) rating above 100kV/μs between the input side and output driver. These advanced features enable high efficiency, high power density, and robustness for a wide variety of power applications.
The MP18831 integrates dual-channel gate drivers in one package. Each output can be grounded to the separated grounds, or connected to a positive or negative voltage reference. The secondary topology can be configured as a half-bridge high-side (HS) and low-side (LS) driver, which are each controlled by two independent input signals. To prevent shoot-through in the half-bridge driver, the MP18831 provides a configurable dead time (DT) set via an external resistor.
A wide primary-side VDDI supply voltage (VDDI) range makes the driver suitable to be interfaced with 3.3V and 5V digital controllers. The secondary-side driver can accept up to a 30V supply. All of the supply voltage pins feature multiple under-voltage lockout (UVLO) protection options.
The MP18831 is available in SOIC-16 NB (narrow body), SOIC-16 WB (wide body), and LGA-13 (5mmx5mm) packages.
