ams AS8506 Cell Monitor and Cell Balancer IC

ams AS8506 Cell Monitor and Cell Balancer IC

ams AS8506 Cell Monitor and Cell Balancer IC enables autonomous cell balancing, simultaneous cell voltage comparison and simplified readout of cells all in a robust, simple and small solution. The AS8506 features simultaneous cell voltage comparison with upper and lower threshold, active or optionally passive cell balancing by simultaneous comparison of actual cell voltages with a target cell voltage. Cells which are below target will either cyclically receive charge packages from an isolated DC-DC converter or, optionally, cells above target will cyclically be discharged by an external resistor through integrated switches in an autonomous way. The device can flexibly be used for battery stacks of 3 and up to 7 cells. Together with autonomous monitoring and balancing this significantly reduces data communication compared to existing solutions and improves EMC robustness.

Features
  • Simultaneous cell voltage capture for balancing and SOA monitoring
  • Autonomous balancing and SOA monitoring strongly reduces data communication and data processing and thereby improves EMC robustness
  • Active charge balancing with very few external components for good efficiency and little heat dissipation
  • Absolute cell voltage readout for OCV capture and cell impedance calculation. Readout of 2 temperature sensors

Applications
  • Mobility like automotive applications 12V and 48V, motorcycles, E-scooters, E-Bicycles, E-Karts
  • Consumer Electronics like Powertools (e.g. drill machines)
  • Off/On-grid energy storage ( for photo voltaic / wind energy)

ams AS8506 supports Cell Monitoring and Cell Balancing in a simultaneous and autonomous way. Additionally the IC can do either passive balancing or active balancing through a small external fly back converter. Each kit demonstrates the AS8506’s ability to operate without a microcontroller and firmware. The AS8506-DK-ST Demo Kit is a standalone balancer kit. The AS806-DK-PASSIVE Demo Kit is configured for Passive Balancing. The AS8506-DK-ACTIVE Demo Kit is configured for Active Balancing. Each kit allows balancing of up to 7 cells completely autonomous. The hardware will support li-based cell packs as well as EDLCs. The number of cells, target voltage as well as over and under voltage can be configured by resistor options.


Applications
  • Mobility like automotive applications 12V and 48V, motorcycles, E-scooters, E-Bicycles, E-Karts
  • Consumer Electronics like Notebooks
  • Powertools like drill machines
  • Off/On-grid energy storage like street lighting




ams USB-INTERFACE-BD USB Interface Board

ams USB-INTERFACE-BD USB Interface Board creates a the link between ams demo boards and the USB interface on the PC. The demo board is used in conjunction with a number of different demo boards that are available. It supports SPI, I2C, UART, CAN and LIN as well as normal GPIO Interfaces and passed them onto the USB Port. The Protocol to the PC side is AMS-Stream via USB-HID and the appropriate driver which is a built-in in modern Operating System. The kit consists of the dual layer PCB USB Interface Board, a USB Cable, and a HDMI Type-D to Type-C Cable which is used to connect to the demo board.
