isl83202 is a medium-frequency h-bridge fet driver from isl company. Its rated voltage is 55v and its driving current is 1a, which is used to drive high- and low-side n-channel mosfets in medium-voltage applications. It is optimized for pwm motor control and uninterruptible power supply systems, and isl83202 enables simple and flexible bridge-based design. With typical input-to-output propagation delays as low as 25ns and with a user-programmable dead-time range of 0.1µs to 4.5µs, the isl83202 is ideal for switching frequencies up to 200kHz. The dead-time of the isl83202 is programmable via a single resistor. The isl83202's four independent driver control inputs (ali, ahi, bli, and bhi) allow driving of every possible switch combination except those that would cause a shoot-through condition. A global disable input, dis, overrides input control and causes the isl83202 to refresh the bootstrap capacitor when pulled low. Integrated undervoltage protection and shoot-through protection ensure reliable system operation. The isl83202 is available in compact 16 Ld soic and 16 Ld PDIP packages and operates over the range of -55°c to +125°c.
The ISL83202 H‑Bridge driver is designed for PWM motor control and UPS systems, offering up to 1 A typical peak drive current and fast 25 ns propagation delays. It features a user‑programmable dead‑time from 0.1 ps to 4.5 µs and integrated undervoltage and shoot‑through protection.
Available in 16‑lead SOIC and PDIP packages, the device operates from –55 °C to +150 °C and supports supply voltages from –0.3 V to 16 V. Detailed pin descriptions, timing diagrams and performance curves are provided for designers.
