ルネサスがDialogを買収か、、、Dialog semiconductorと言えば昔はiPhoneの電源管理IC(PMIC)を供給してたのが全部Appleに売却して、自身はいろいろ買収したりして、一体何のビジネスをするのかと思っていたらこうなった、、、

ダイアログからリークされた話、ルネサスが正式に買収をプレスリリースしていた。

ルネサスがDialog社を買収し、 組み込みソリューションでのグローバルリーダーシップを強化

ルネサスのことはとりあえずおいておいて、Dialogについて。

かつてはiPhoneの電源管理IC（PMIC=Power Management IC)と言えばDialogがずっと共有していた。

iPhone6Sとかはこんな感じ。

ところが、AppleがDialogのその電源管理ICを作っているところだけを買収した。

Apple gets critical iPhone technology in $600 million Dialog deal

そこからICにリンゴマークがつくようになった（写真はiPhone 12 Pro Max)。

で本体は何を残したかというと、Bluetooth　LEやモバイル以外のPMICをやっていたが、

どうも存在感がイマイチ。そのためか実は買収はめっちゃ多い会社だった。

• 2011 - VoIP and wireless chipmaker SiTel Semiconductor for $86.5 million.^[14]
• 2013 - Dialog acquired iWatt Inc, which had filed for an IPO the prior year, for roughly $345 million, paying $310 million in cash and pledging an additional $35 million in contingent considerations.^[15][16]
• 2015 - Dialog made a $4.6 billion for Atmel.^[17] This acquisition was cancelled in January 2016 when Atmel instead agreed to be purchased by Microchip for $3.56 billion in cash and stock.^[18] To break the agreement, Atmel paid Dialog a termination fee of $137.3 million.^[19]
• 2017 - Silego Technology, a maker of configurable mixed-signal integrated circuits (CMICs), for $306 million, of which $276 would be paid in cash, with an additional contingent consideration of up to $30.4 million. The deal added consumer electronics companies like Fitbit, Garmin, and GoPro to Dialog's roster of customers.^[20]

• 2020 - Dialog bought US-based Adesto, a provider of application-specific semiconductors and embedded systems for the Industrial IoT, for $500 million.^[28]

ルネサスと車載で協業するもパッとしない、、、と思ったらルネサスに買われることに。

大丈夫かな、、、両方とも。
