ANALOG CONTROL AND PROTECTION
CIRCUITRY:
The on-chip voltage regulator supplies 3.3 V to the internal
logic. The charge pump provides gate drive for the H-Bridge
MOSFETs. The current and temperature sense circuitry
provides detection and protection for the output drivers.
Output under-voltage protection shuts down the MOSFETS.
GATE CONTROL LOGIC:
The 33926 is a monolithic H-Bridge Power IC designed
primarily for any low voltage DC servo motor control
application within the current and voltage limits stated for the
device. Two independent inputs provide polarity control of
two half-bridge totem-pole outputs. Two independent disable
inputs are provided to force the H-Bridge outputs to tri-state
(high-impedance off-state).
H-BRIDGE OUTPUT DRIVERS: OUT1 AND OUT2
The H-Bridge is the power output stage. The current flow
from OUT1 to OUT2 is reversible and under full control of the
user by way of the Input Control Logic. The output stage is
designed to produce full load control under all system
conditions. All protective and control features are integrated
into the control and protection blocks. The sensors for current
and temperature are integrated directly into the output
MOSFET for maximum accuracy and dependability.
