Texas Instruments SN6505A | Demoboard TIDA-020019
Automotive isolated CAN and power front end reference design
Details
| Topologie | Gegentaktflusswandler |
| Eingangsspannung | 5 V |
| Ausgang 1 | 5 V / 1 A |
| IC-Revision | E1 |
Beschreibung
This reference design demonstrates reinforced isolated CAN communication, which is widely used in automotive environments, in a small footprint. In hybrid and electric vehicles (HEV/EVs), a complete high-voltage network is floating with respect to the chassis ground. Isolation is required for the power and communication channels interfaced between floating high- to low-voltage systems. This TI design has a low transmission delay, which reduces the loop delay and supports higher baud rates of the CAN.
Eigenschaften
- Integrated CAN and digital isolator (ISO1042-Q1)
- Low loop delay (typically 139 ηs) to support high-speed arbitration rates
- Inbuilt reinforced digital isolation
- ±70-V bus fault protection
- Compliant with ISO 11898-2 CAN standard
Typische Anwendungen
- Starter/Generator, Battery Management Systems, Onboard Chargers
- DC/DC Converters
