DESCRIPTION
The PH5551A2NA1-E4 is a digital ambient illuminance sensor for I 2C bus interfaces and includes a 16-bit AD converter. This product has spectral characteristics close to human eye sensitivity and outputs digital signals corresponding to the ambient brightness. The PH5551A2NA1-E4 can be used to improve the performance and reduce the power consumption of digital equipment such as FPD TV sets and mobile phones, by enabling automatic brightness control and automatic switching on and off of lighting systems.

01 Measurement Register Control Register Measurement Register
10 Measurement Register Measurement Register
(2) AP_CNT: Address Pointer Control Code Description 00 The address is fixed to the register address specified by ADR_PTR. 01 The register address is incremented when one item of data is written or read. 10 If these bits are read after being written, the current register address is output. (3) ADR_PTR: Register Address Specify the address of the register to be written or read by using these 3 bits. (4) PWR: Power On/Power Down Power on/Power down (1: Power on)

The ADC enters standby mode.(1: Stop) INT_COUNT : How many times the upper or lower threshold value is exceeded in succession before an interrupt signal is generated. (00: Once; 01: 4 times; 10: 8 times; 11: 16 times) INT_AT_RT : Automatic restoration from interrupt enable/disable (0: Processing automatically restored; 1: Processing not automatically restored (restored after the interrupt is cancelled by the system)) INT_EN : Interrupt enable/disable (0: Disable interrupts; 1: Enable interrupts) 3.
