description (continued)
less than 300 ns, even at maximum output current. Overcurrent shutdown and crossover protection combine
to eliminate destructive faults in the output MOSFETs, thereby protecting the processor during operation. The
slowstart current source is proportional to the reference voltage, thereby eliminating variation of the slowstart
timing when changes are made to the output voltage. When the output drops to less than 93% of the nominal
output voltage, PWRGD will pull the open-drain output low. The overvoltage circuit will disable the output drivers
if the output voltage rises more than 15% above the nominal output voltage. The TPS56100 also includes an
inhibit input to control power sequencing and undervoltage lockout thereby insuring the 5-V supply is within
limits before the controller starts. The 2-A MOSFET drivers can power multiple MOSFETs in parallel to drive
single or multiple DSPs and load currents up to 30 A. The high-side driver can be configured as a
ground-referenced driver or as a floating bootstrap driver with the included internal bootstrap Schottky diode.
The TPS56100 is available in a 28-pin TSSOP PowerPAD package, which increases thermal efficiency and
eliminates bulky heat sinks.
