5 Pin Configuration and Functions

Table 5-1 Pin Functions
PIN I/O(1) DESCRIPTION
NO. NAME
1 GND — Device ground.
2 SNS O Sense current output. Use a parallel RC network to the GND pin of the IC.
3 VDD P Logic supply input. Closely decouple to the GND pin of the IC with a ceramic 1-µF capacitor.
4 DI I Sets the output behavior in the LIMP HOME mode, if configured as such. The pin needs to be connected to MCU or other HI/LO source through a 10-kΩ resistor for protection and enabling the reverse polarity FET turn-on function.
5 LHI I Externally enables the LIMP HOME mode.
6, 7, 8 VOUT1 O Output of channel 1.
9,10, 11 VOUT2 O Output of channel 2.
12 FLT ,WAKE_SIG O Fault output (active low), indicating faulton any (one or more) channel. Open drain, pull up with a 4.7-kΩ resistor to the VDD pin. Also functions as a wake signal to the MCU upon load current demand in Low Power Mode or the vehicle key-off mode.
13 SDI I SPI device (secondary) data input.
14 SDO O SPI data output from the device. Internally pulled up to VDD.
15 CS I SPI interface chip select (active low). Internally pulled up to VDD.
16 SCLK I SPI interface clock input to the device.
Exposed pad VBB P Power supply input.
(1) I = input, O = output, P = power
