detailed description (continued)
IN
The IN terminal is a TTL-compatible digital terminal that is the input control signal for the drivers. The
TPS2838/48 have noninverting inputs; the TPS2839/49 have inverting inputs. On the TPS2838 and TPS2848,
a high on IN results in a high on HIGHDR. On the TPS2839 and TPS2849, a high on IN results in a low on
HIGHDR.
SYNC (TPS283x only)
The SYNC terminal controls whether the drivers operate in synchronous or nonsynchronous mode. In
synchronous mode, the low-side FET is operated as a synchronous rectifier. In nonsynchronous mode, the
low-side FET is always off. SYNC is a TTL-compatible digital terminal.
PWRRDY
Depicts the status of the V
CC
pin voltage and the driver regulator output on the open-drain PWRRDY pin.
DELAY
Adjustable high-side turnon delay from from when the low-side FET is turned off.
ADJ (TPS283x only)
Input for adjusting the driver regulator output. See the
application information
section for the adjustment formula.
