Independent of V
+
, low-voltage GPIO-compatible control inputs
TS5A21366 integrates special control inputs with low threshold allowing the device to be controlled by 1.8-V
signals. The thresholds are fixed and independent of the supply value (V
+
). The low threshold (V
IH
, V
IL
) of the
control inputs (IN1, IN2) is achieved by use of an internal bias circuit. To avoid an increased quiescent current
(I
+
) condition, proper power sequencing must be followed to ensure that the bias circuitry is powered up prior to
applying voltage on the I/Os. The proper sequence is for the V
+
pin to be brought up to V
+
before the control
inputs (IN1, IN2) are allowed to go to a high level.
