To provide a brake drive control circuit controlling an electromagnetic brake provided in a robot, etc., which can make applied voltage to a high-side switch into relatively low voltage without impairing safety, and dispenses with providing a separate power supply circuit of a large capacity.SOLUTION: A brake drive control circuit controlling an electromagnetic brake, which releases braking following electrification, comprises: a first rectification element provided between a first power supply of a first circuit voltage and one terminal of the electromagnetic brake; a shutoff switch inserted into a line for supplying power to the first power supply; a first switching element provided between the other terminal of the electromagnetic brake and a grounding point; and a second switching element and a second rectification element provided in series between the one terminal of the electromagnetic brake and a second power supply of a second circuit voltage different from the first circuit voltage.SELECTED DRAWING: Figure 1

    【課題】ロボットなどに設けられる電磁ブレーキを制御するブレーキ駆動制御回路において、安全性を損なうことなく、ハイサイドスイッチへの印加電圧を比較的低い電圧とすることができ、かつ、大容量の別個の電源回路を設けることを不要とする。【解決手段】通電することによりブレーキを解除する電磁ブレーキを制御するブレーキ駆動制御回路は、第1回路電圧の第1電源と電磁ブレーキの一方の端子との間に設けられた第1整流素子と、第1電源に電力を供給するラインに挿入された遮断スイッチと、電磁ブレーキの他方の端子と接地点との間に設けられた第1スイッチング素子と、第1回路電圧とは異なる第2回路電圧の第2電源と電磁ブレーキの一方の端子との間で直列に設けられた第2スイッチング素子及び第2整流素子と、を備える。【選択図】図1
