2 / 28 page Analog Integrated Circuit Device Data 2 Freescale Semiconductor 33298 INTERNAL BLOCK DIAGRAM INTERNAL BLOCK DIAGRAM Figure 2. 33298 Simplified Block Diagram Table 1. Fault Operation SERIAL OUTPUT (SO) PIN REPORTS Over-voltage Over-voltage condition reported Over-temperature Fault reported by Serial Output (SO) pin Over-current SO pin reports short to battery/supply or over-current condition Output ON, Open Load Fault Not reported Output OFF, Open Load Fault SO pin reports output OFF open load condition DEVICE SHUTDOWNS Over-voltage Total device shutdown at VPWR = 28 to 36V. All outputs are latched off while the SPI register is reset (cleared). Outputs can be turned back on with a new SPI command after VPWR has decayed below the over-voltage shutdown voltage including hysteresis. Over-temperature Only the output experiencing an over-temperature condition turns off. Over-current Only the output experiencing an over-current condition shuts down at 3.0A to 6.0A after a 25ms to 100ms delay, with SFPD pin grounded. All outputs will continue to operate in a current limit mode, with no shutdown, if the SFPD pin is at 5.0V.
