Diamond Electronics Ltd are introducing MORNSUN’s new SMD DC/DC converter module, CF0505XT-1WR2 aimed at Battery Management System (BMS) applications within the Automotive market.
Designed specifically for automotive applications with ultra-wide operating temperature range of -50℃-+125℃, meeting the highest temperature of automotive standards. The CF0505XT is different from automotive IC launched by some semiconductor companies as it is a plug and play power supply which reduces component count and the complexities of additional circuit design.
With 3.5KVDC isolation voltage and 8KVDC antistatic protection voltage, CF can easily meet the high isolation and static level requirements of complex automobile electronic environment. Due to its unique short circuit protection technology, CF can cut off the output voltage quickly to protect the device when the load shorts out for a long time.
Because of ultra-high temperature resistance performance, CF can be used in vehicle communication system, engine control system, ignition system, motor voltage monitoring, electronic accelerator pedal, automobile tire pressure detection system, doors and tail lights controller, air conditioning control and battery management system (BMS),
- 12.7 x 8.5 x 7.25 mm SMD Package
- Input & Output voltage: In: 4.5-5.5V, Out: 5V/200mA
- Operating temp. range: -50~125℃
- Isolation voltage: 3500VDC
- Short circuit protection (continuous, self-recovery)
- Meet UL/EN60950
- Meet AEC-Q100 standard
- Meet TS16949 system standard
The Battery Management System (BMS) is used to monitor and control the charging and discharging of electric car batteries . The CB0505XT-1W to realize double isolation of power supply and signal hence improving the reliability of the battery monitoring.
In the motor voltage monitoring system where requirements for isolation and temperature are high, the temperature is normally above 100℃ due to the severe motor heating. Before, Previous module had maximum temperature limit 105℃, but now the operating temperature of CF0505XT-1WR2 is up to 125 ℃, increasing the reliability of power supply module when working under high temperature environment.
Moreover, with the isolation voltage reaching 3500VDC, it meets the high isolation requirement of the system. In the application below, the motor driver uses dedicated module of MORNSUN IGBT products QA04 to power the motor driver and ensure the stability and reliability of the system.
