Applications

Typical Application Circuit ÿ Gate drive circuit for B6-NMOS bridge ÿ IC supply voltage range 5V(7V) to 28V (peak 42V) ÿ Sleep mode current 20µA (typ.) ÿ LIN2.x - transceiver, compatible down to LIN1.3 ÿ Re-FLASH-able via LIN (normal/high-speed mode) ÿ SPI-Adjustable over-current switch-off threshold ÿ SPI-Programmable 6 * FET short circuit detection ÿ Over-/under voltage protections ÿ 16 bit RISC CPU assisted by waveform booster ÿ 32k byte FLASH, 4k byte SRAM ÿ 10 bit 1 Msample SAR ADC ÿ 3 * 16 bit PWM generation (edge/center aligned) ÿ Dynamical SPI-Programmable dead-time generation ÿ Adjustable window watchdog (independent clock) ÿ Tjunction -40°C up to +125°C ÿ BLDC HVAC fans, Engine cooling fans ÿ BLDC Fuel pumps, Hydraulic pumps, Oil pumps ÿ BLDC Turbo charger adjustment, positioning systems ÿ Multiple DC motor control ÿ Without external FETs: direct driving of small loads General Description This IC controls up to 3 NMOS half bridges for driving BLDC motors or other loads. It’s also possible to drive loads directly at battery supply. For controlling the mo- tor a dynamically programmable, precise dead time gen- eration and a current amplifier are implemented. Diag- nostic functions are detecting over current (dynamically programmable threshold), over-temperature, over-/ un- der-voltage and short-cuts, one for every FET (HS and LS with different dynamically programmable threshold). Product versions with a “state of the art” LIN2.x trans - ceiver or with a PWM-interface are available. The LIN in- terface supports “FLASH Mode” to upload a new firm- ware. The LIN UART is compatible to LIN2.1. The IC provides an integrated 16 bit RISC CPU, assited by hardware waveform generation. Development tools are available. Motor commutation can be done with hall-sensors or other sensor-less principles.
