DETAILED COMPONENT OPERATION AND PERFORMANCE
POWER SUPPLIES
Three I/O pins are used to supply power to the chip:
1) Two DRVP (referenced to DRVN) for the output stage.
2) VCC (referenced to VEE) for all other functions.
VCC and DRVP are at 5V ± 10%. The two supplies are routed from separate pins to prevent power stage switching spikes
from interfering with the chip’s other circuits. VCC is specified to draw a maximum of 4.0mA under normal operating
conditions.
For protection against inadvertent over/undervoltages, the chip’s input pins are diode clamped to the supply rails through
current limiting resistors.
Undervoltage Lockout
The chip includes an internal undervoltage lockout circuit with built in hysteresis and a logic level power good indicator.
The positive and negative going thresholds are nominally 4.1V and 3.5V, respectively. If Vcc is below this range, the
oscillator, error amplifier, main comparators, and output drive circuits are all disabled. The power OK indicator is active
high (logic ''1'') when a valid supply voltage is applied.
Shutdown Logic
The chip has two logic level inputs for implementing shutdown functions. Asserting a logic ''1'' on the SLEEP pin disables
all chip functions and puts the chip into a very low power consumption mode. Asserting a logic ''0'' on the EN pin shuts
down all functions except the reference, bias generators, and auxiliary amplifier.
