POWER MODULE WITH HIGH-SIDE AND LOW-SIDE PROGRAMMABLE CIRCUIT
First Claim
1. A power module comprising:
- a first switching element and a second switching element that are connected in a half-bridge configuration;
a high-side circuit that drives the first switching element;
a low-side circuit that drives the second switching element;
a high-side programmable circuit that is configured to implement a first logic function or parameter to be used by the high-side circuit;
a low-side programmable circuit that is configured to implement a second logic function or parameter to be used by the low-side circuit;
a write port that inputs a control signal including write data to be written to the high-side programmable circuit and the low-side programmable circuit and a selection signal;
internal wiring that connects the high-side programmable circuit and the low-side programmable circuit, and a level shifter that is provided in the internal wiring, wherein;
when the control signal is input to the write port, the control signal is transferred to the high-side programmable circuit via the level shifter or the low-side programmable circuit; and
whether the write data is written to the high side programmable circuit or the low-side programmable circuit is implemented according to the selection signal.

Abstract
A power module including first and second switching elements connected in a half-bridge configuration, an integrated circuit including high-side and low-side circuits that respectively drive the first and second switching elements, high-side and low-side programmable circuits that are respectively configured to implement first and second logic functions or parameters to be used by the high-side and low-side circuits. The integrated circuit includes a write port that receives data to be written to the high-side and low-side programmable circuits, internal wiring that connects the high-side and low-side programmable circuits in a daisy chain configuration, and a level shifter that is provided in the internal wiring connecting the low-side programmable circuit to the high-side programmable circuit, and that connects a low-side signal system and a high-side signal system.
