MPQ2977-AEC1

Digital 6-Phase Controller with Serial Interface, AEC-Q100 Qualified

Datasheet

Description

The MPQ2977 is a two-rail, digital, multi-phase controller for autonomous driving applications. The device can work with MPS’s Intelli-Phase^TM products to complete the multi-phase voltage regulator (VR) solution with minimal external components. It can be configured for up to 6 phases for two-rail operation.

The MPQ2977 provides memory to store and restore device configurations. Device configurations and fault parameters can be configured and monitored via the serial interface. The MPQ2977 monitors and reports the output current (I_OUT) via the current-sense (CS) output from the Intelli-Phase^TM products.

The MPQ2977's unique, digital, multi-phase, nonlinear control provides fast transient response to the load transient with a minimal number of output capacitors. With only one power loop control method for both the steady state and load transient response, power loop compensation is simple to configure.

The MPQ2977 is available in a TQFN-40 (6mmx6mm) package.

The MPQ86940 is a monolithic half-bridge with built-in, internal power MOSFETs and gate drivers. It can achieve up to 40A of continuous output current (I_OUT) across a wide input voltage (V_IN) range. The integrated MOSFETs and drivers achieve high efficiency through an optimized dead time (DT) and reduced parasitic inductance.

The MPQ86940 is compatible with tri-state output controllers. It also includes general-purpose current sensing and temperature sensing. The MPQ86940 is ideal for autonomous driving applications where efficiency and compact size are at a premium.

The MPQ86940 is available in a TQFN-21 (4mmx5mm) package.
