DESCRIPTION
Analog ground
High side bootstrap supply (BST), external capacitor to OUT_A required
High side bootstrap supply (BST), external capacitor to OUT_B required
High side bootstrap supply (BST), external capacitor to OUT_C required
Ground
Power ground for half-bridge A
Power ground for half-bridge B
Power ground for half-bridge C
Gate-drive voltage supply
Gate-drive voltage supply
Gate-drive voltage supply
Mode selection pin
Reserved mode selection pin, AGND connection is recommended
Reserved mode selection pin, VREG connection is recommended
No connection pin. Ground connection is recommended
Analog overcurrent programming pin, requires resistor to AGND
Overtemperature warning signal, open-drain, active-low. An internal pull-up resistor to
VREG (3.3 V) is provided on output. Level compliance for 5-V logic can be obtained by
adding external pull-up resistor to 5 V
Output, half-bridge A
Output, half-bridge B
Output, half-bridge C
Power supply input for half-bridge A requires close decoupling capacitor to ground.
Power supply input for half-bridge B requires close decoupling capacitor to gound.
Power supply input for half-bridge C requires close decoupling capacitor to ground.
Input signal for half-bridge A
(1) I = input, O = output, P = power, T = thermal
