DESCRIPTION
Pullup
3.3-V Analog power supply
Analog 3.3-V supply ground
Active low. A back-end error sequence is initiated by applying a logic
low to this pin. Connect to an external power stage. If no external
power stage is used, connect directly to DVDD.
High-side bootstrap supply for half-bridge A
High-side bootstrap supply for half-bridge B
(1) TYPE: A = analog; D = 3.3-V digital; P = power/ground/decoupling; I = input; O = output
(2) All pullups are 20-µA weak pullups and all pulldowns are 20-µA weak pulldowns. The pullups and pulldowns are included to assure
proper input logic levels if the terminals are left unconnected (pullups → logic 1 input; pulldowns → logic 0 input). Devices that drive
inputs with pullups must be able to sink 50 µA while maintaining a logic-0 drive level. Devices that drive inputs with pulldowns must be
able to source 50 µA while maintaining a logic-1 drive level.
(3) If desired, low-ESR capacitance values can be implemented by paralleling two or more ceramic capacitors of equal value. Paralleling
capacitors of equal value provides an extended high-frequency supply decoupling. This approach avoids the potential of producing
parallel resonance circuits that have been observed when paralleling capacitors of different values.
