BTS730 PWM Power Unit is a high-side switch (bootstrap) that enables continuous power control for lamps, LEDs or inductive loads. Features of the product include overtemperature protection, short circuit / overload protection, load dump protection, undervoltage and overvoltage shutdown with auto-restart and hysteresis, reverse battery protection, adjustable timing frequency, controlled switching rise and fall times, internally limited maximum current, protection against loss of GND, and ESD protection. The product is available in P-DSO-20-6 (SMD) package.
The BTS730 is a PWM power unit that enables continuous power control for lamps, LEDs, and inductive loads. It features a high‑side switch with bootstrap operation, over‑temperature protection, short‑circuit/overload protection, load‑dump protection, undervoltage and overvoltage shutdown with auto‑restart, reverse‑battery protection, ESD protection, and ground‑loss detection.
The device is supplied in a P‑DSO‑20‑6 (SMD) package and operates from –40 °C to +150 °C. Key electrical parameters include an on‑state resistance of about 70 mΩ, a PWM frequency range of 50‑100 Hz, a maximum pulse duty factor of 95‑98 %, and protection thresholds such as 3‑5.4 V for undervoltage shutdown and 17‑19 V for overvoltage shutdown. Detailed pin definitions, block diagram, and application notes for dashboard lighting dimming are also provided.
