減電圧保護回路内蔵 Under Voltage Protection Circuit

VDD=2.0V以下、及びVDDA=3.0V以下で 減電圧保護が機能します。 The UVLO circuit activates when VDD<2.0V and VDDA is lower than 3.0V

過電流保護回路内蔵 Built-in Overcurrent Protection Circuit

Typ.1.0A電流制限動作が機能し、 SO端子よりフラグを出力します。 Limits current to 1.0A (typ.) and outputs a flag from the SO pin

過熱保護 Thermal Shutdown

Typ.175でサーマルシャットダウン機能します。(自己復帰) Initiates when the temperature reaches 175°C (typ.) (auto-recovery)

オープン検出保護回路内蔵 Built-in Open Detection

OUT端子電圧が1.5V以下になるとオープン検出機能が働き、SO端子よりフラグを出力します。 Operates when the output voltage drops below 1.5V and outputs a flag output from the SO pin
