Table 36. External Temperature Register ADC (0x42)

Address

and Bit

R/W

Default

Value

Function and Description

0x42 [15:12]

Reserved

0x42 [11:0]

NtcTemp

12-bit raw data of the thermistor ADC reading on GP2 pin.

Vol_gp2 = NtcTemp / 4095 * 10 * 2.1(V)

Table 37. IOut Register (0x44)

Address

and Bit

R/W

Default

Value

Function and Description

0x44 [15:0]

IOut

In RX mode the AP may read this register to get current Iout level in mA.

In TX mode the register holds the Power Supply current Iin in mA.

Table 38. Die Temperature Register (0x46)

Address

and Bit

R/W

Default

Value

Function and Description

0x46 [15:0]

DieTemp

12bit of current Die Temperature ADC value. Formula converting ADC value to

Die Temperature in Celsius Degree is t_die [degC] = (ADC code * 0.075) - 174.

Table 39. AC Period Register (0x48)

Address

and Bit

R/W

Default

Value

Function and Description

0x48 [15:0]

ACPeriod

Read back the AC Period. The value is presented by number of 6MHz clocks per 64

AC cycles.

The AC frequency can be calculated as:

F(kHz) = 64 * 6000 / ACPeriod;

ILim

0x0E

Set main LDO current limit in 0.1A steps. The limit level is set to the value plus 0.1A.

Table 41. Signal Strength Packet (0x4B)

Address

and Bit

R/W

Default

Value

Function and Description

0x4b [7:0]

SignalStrength

Signal Strength Packet sent by 9415 at beginning of power transfer
