Note:(*) Analog sense current drift is deviation of factor K for a given device over (-40°C to 150°C and 9V<VCC<16V) with respect to it’s
value measured at Tj=25°C, VCC=13V.
WAVEFORMS AND TRUTH TABLE
Table 14. Truth Table In Normal Operating Conditions
In normal operating conditions the DIAGX/ENX pin is
considered as an input pin by the device. This pin must be
externally pulled high.
PWM pin usage:
In all cases, a “0” on the PWM pin will turn-off both LSA
and LSB switches. When PWM rises back to “1”, LSA or
LSB turn on again depending on the input pin state.
