Initial Release
Updated specifications for current sense amplifier and overcurrent comparator
Added Gain/Phase curves for current sense amplifier
Added typical curves for load margin on Px_CBOOT
Added discussion about bootstrap capacitors and requirements for external bootstrap diodes
Updated application drawings
Added VSUP requirement for hold-off
Updated Freescale form and style
Added note to VLS Regulator Outputs (VLS, VLS_CAP)
Changed Charge Device Model - CDM
Corrected title to No output loads on Gate Drive Pins, No PWM, Outputs initialized
Changed In order to achieve a 100% duty cycle operation of the High Side external FETs, a fully
integrated trickle charge pump provides the charge necessary to maintain the external FET gates
at fully enhanced levels. The trickle charge pump has limited ability to supply external leakage paths
while performing it’s primary function. The graph in Figure 11 shows the typical margin for supplying
external current loads. These limits are based on maintaining the voltage at CBOOT at least 3.0 V
greater than the voltage on the HS_S for that phase. If this voltage differential becomes less than
3.0 V, the corresponding high side FET will most likely not remain fully enhanced and the high side
driver may malfunction due to insufficient bias voltage between CBOOT and HS_S. and associated
