  1. Kernel driver ltc4151
  2. =====================
  3. Supported chips:
  4. * Linear Technology LTC4151
  5. Prefix: 'ltc4151'
  6. Addresses scanned: -
  7. Datasheet:

  9. Author: Per Dalen <per.dalen@appeartv.com>
  10. Description
  11. -----------
  12. The LTC4151 is a High Voltage I2C Current and Voltage Monitor.
  13. Usage Notes
  14. -----------
  15. This driver does not probe for LTC4151 devices, since there is no register
  16. which can be safely used to identify the chip. You will have to instantiate
  17. the devices explicitly.
  18. Example: the following will load the driver for an LTC4151 at address 0x6f
  19. on I2C bus #0:
  20. # modprobe ltc4151
  21. # echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device
  22. Sysfs entries
  23. -------------
  24. Voltage readings provided by this driver are reported as obtained from the ADIN
  25. and VIN registers.
  26. Current reading provided by this driver is reported as obtained from the Current
  27. Sense register. The reported value assumes that a 1 mOhm sense resistor is
  28. installed.
