1 Kernel driver ltc4151 2 ===================== 3 4 Supported chips: 5 6 * Linear Technology LTC4151 7 8 Prefix: 'ltc4151' 9 10 Addresses scanned: - 11 12 Datasheet: 13 14 http://www.linear.com/docs/Datasheet/4151fc.pdf 15 16 Author: Per Dalen <per.dalen@appeartv.com> 17 18 19 Description 20 ----------- 21 22 The LTC4151 is a High Voltage I2C Current and Voltage Monitor. 23 24 25 Usage Notes 26 ----------- 27 28 This driver does not probe for LTC4151 devices, since there is no register 29 which can be safely used to identify the chip. You will have to instantiate 30 the devices explicitly. 31 32 Example: the following will load the driver for an LTC4151 at address 0x6f 33 on I2C bus #0:: 34 35 # modprobe ltc4151 36 # echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device 37 38 39 Sysfs entries 40 ------------- 41 42 Voltage readings provided by this driver are reported as obtained from the ADIN 43 and VIN registers. 44 45 Current reading provided by this driver is reported as obtained from the Current 46 Sense register. The reported value assumes that a 1 mOhm sense resistor is 47 installed. 48 49 ======================= ================== 50 in1_input VDIN voltage (mV) 51 52 in2_input ADIN voltage (mV) 53 54 curr1_input SENSE current (mA) 55 ======================= ==================
