It integrates a bootstrap diode rated to 600 V maximum high-side voltage, letting it float the high-side gate drive well above ground in a half-bridge leg — the topology used in motor drives, UPS inverters, and DC-DC converters where the high-side source swings with the switching node. That drive strength handles the gate charge of medium-power IGBTs and MOSFETs in the 30–100 nC range without excessive switching loss, though a higher-current driver is worth considering for paralleled devices or very large die. Supply voltage spans 10 V to 20 V, covering the standard bias rail for industrial gate-drive circuits. The non-inverting input type means the output follows the input polarity: a logic high on the input turns on the corresponding output. That simplifies the firmware mapping compared to inverting drivers that require a logic inversion in the PWM timer. Housed in a 14-pin DIP (0.300-inch, 7.62 mm) with through-hole mounting.","metaTitle":"IR21844 Half-Bridge Gate Driver, 600V Bootstrap","metaDescription":"Infineon IR21844 half-bridge gate driver for IGBT/N-Ch MOSFET. 600V bootstrap, 1.9A source/2.3A sink peak output, 10V-20V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Gate Type":"IGBT, N-Channel MOSFET","Input Type":"Non-Inverting","Channel Type":"Synchronous","Mounting Type":"Through Hole","Package / Case":"14-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"10V ~ 20V","Number of Drivers":"2","Base Product Number":"IR21844","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C ~ 150°C (TJ)","Rise / Fall Time (Typ)":"40ns, 20ns","Supplier Device Package":"14-DIP","Logic Voltage - VIL, VIH":"0.8V, 2.7V","High Side Voltage - Max (Bootstrap)":"600 V","Current - Peak Output (Source, Sink)":"1.9A, 2.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6fe00f96a8f216d35f11f4439898d52e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IR21844/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IR21844","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IR21844 when reusing this data.
