TMD2621 − Register Overview

The PPULSE field sets the maximum number of IR VCSEL pulses

that may occur in a proximity cycle. The proximity engine will

automatically continue to add IR VCSEL pulses, up to the value

set in PPULSE or if a near-saturation condition occurs if

Automatic Pulse Control (APC) is enabled. The dynamic range

of the sensor is automatically adjusted to detect distant targets

as well as prevent saturation from close targets. This operation

also reduces power consumption because proximity

integration period is automatically shortened when a target is

close to the sensor.

If Automatic Pulse Control (APC) is disabled by setting bit 6 in

CFG6 to 1, then PPULSE always determines the number of

proximity pulses to be transmitted.
