It drives two N-channel MOSFETs or IGBTs in a half-bridge configuration: a high-side switch (referenced to the switching node VS) and a low-side switch (referenced to COM). The high-side driver uses a bootstrap technique: an external diode and capacitor create a floating supply (VB-VS) that powers the high-side driver. When the low-side MOSFET is on, VS is near COM, and the bootstrap capacitor charges through the diode from VCC. When the high-side driver turns on, the VB rail floats above VS, and the capacitor provides power. The internal level shifter translates the INA logic signal (referenced to COM) to the high-side driver (referenced to VS). Cross-conduction prevention (dead time) must be managed externally by the PWM controller. The UVLO (under-voltage lockout) on both VCC and VB prevents gate drive when supply voltage is insufficient to fully enhance the MOSFET, preventing linear-mode operation and excessive dissipation. Propagation delay is 80ns typical.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>INA<\/td><td>Input<\/td><td>Channel A logic input<\/td><\/tr><tr><td>2<\/td><td>INB<\/td><td>Input<\/td><td>Channel B logic input<\/td><\/tr><tr><td>3<\/td><td>VCC<\/td><td>Power<\/td><td>Logic supply (10-20V)<\/td><\/tr><tr><td>4<\/td><td>COM<\/td><td>Power<\/td><td>Common return (ground for logic side)<\/td><\/tr><tr><td>5<\/td><td>VB<\/td><td>Power<\/td><td>High-side floating supply (bootstrap cap)<\/td><\/tr><tr><td>6<\/td><td>HO<\/td><td>Output<\/td><td>High-side gate drive output<\/td><\/tr><tr><td>7<\/td><td>VS<\/td><td>Power<\/td><td>High-side floating return (switching node)<\/td><\/tr><tr><td>8<\/td><td>LO<\/td><td>Output<\/td><td>Low-side gate drive output<\/td><\/tr><\/table>","application_scenarios":"<li>Industrial control<\/li><li>Consumer electronics<\/li><li>Communication equipment<\/li><li>Power management<\/li>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Infineon<\/td><td>IRS4427STRPBF<\/td><td>SOIC-8<\/td><td>Same device, Infineon label<\/td><\/tr><tr><td>Infineon<\/td><td>IR2110PBF<\/td><td>DIP-14<\/td><td>Half-bridge driver, 500V, 2A<\/td><\/tr><tr><td>Texas Instruments<\/td><td>LM5109BSD\/NOPB<\/td><td>SOIC-8<\/td><td>Half-bridge driver, 90V, 1A<\/td><\/tr><tr><td>Silicon Labs<\/td><td>Si8235AB-D-IS1<\/td><td>SOIC-16<\/td><td>Isolated half-bridge, 4A<\/td><\/tr><tr><td>onsemi<\/td><td>NCP5183DR2G<\/td><td>SOIC-8<\/td><td>Half-bridge driver, 600V, 1.8A<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/5829","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=5829"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/5829\/revisions"}],"predecessor-version":[{"id":5979,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/5829\/revisions\/5979"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=5829"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=5829"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=5829"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=5829"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
