Current Waveform in Mixed (Slow
+ Fast) Decay Mode
Timing charts may be simplified for explanatory purposes.
When a current value increases (Mixed-Decay point is fixed to 37.5%)
When a current value decreases (Mixed-Decay point is fixed to 37.5%)
The Charge period starts as the internal oscillator clock starts counting. When the output current reaches the
predefined current level, the internal RS comparator detects the predefined current level (NF); as a result, the IC
enters Slow-Decay mode.
The TB62214FG/FTG transits from Slow-Decay mode to Fast-Decay mode at the point 37.5 of a PWM
frequency (one chopping frequency) remains in a whole PWM frequency period (on the rising edge of the 11th
clock of the OSCM clock).
When the OSCM pin clock counter clocks 16 times, the Fast-Decay mode ends; and at the same time, the
counter is reset, which brings the TB62214FG/FTG into Charge mode again.
Note: These figures are intended for illustrative purposes only. If designed more realistically, they would show
transient response curves.

The IC enters Charge mode for a moment at which
the internal RS comparator compares the values.
The IC immediately enters Slow-Decay mode
because of the current value exceeding the
