I/O

DESCRIPTION

CS

8 (10)

I

Chip select. The CS is an active-low input used to select the serial interface of the device. The device accepts

serial input data and transmits fault data when CS is held low. An internal pullup resistor is provided on the CS

input.

DRAIN3

DRAIN4

DRAIN5

10 (12)

9 (11)

2 (2)

1 (1)

O

FET drain outputs. The DRAIN terminals are low-side switches for inductive and resistive loads. Each output

provides an internal drain-gate clamp to snub inductive transients.

GND

5, 6, 15,

16 (5, 6, 7,

8, 17, 18,

19, 20)

O

Ground. These terminals provide ground return paths for the device.

SCLK

3 (3)

I

Serial clock. The SCLK clocks the shift register. Serial data is transferred into the SDI port and serial fault data

is transferred out of the SDO port of the device on the rising edges of SCLK.

SDI

4 (4)

I

Serial data input. The device receives serial data from the control device using the SDI. Serial input data can

be configured in 8-bit or 16-bit data words. Refer to Figures 2 and 4 for input protocol. An internal pulldown

resistor is provided on the SDI input.

SDO

7 (9)

O

Serial data output. This 3-state output transfers fault data to the control device after the device has been

selected by the CS terminal.

Vbat

20 (24)

I

Battery voltage. The Vbat terminal monitors the battery voltage to detect over-voltage conditions.

VCC

11 (13)

I

Supply voltage. The VCC terminal receives a 5-V supply for internal logic.

† Terminal numbers listed in parenthesis are for the 24-pin DW package.

‡ Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values are with respect to GND.

2. Each power DMOS source is internally connected to GND.

3. Pulse duration

≤ 100 µs and duty cycle ≤ 2%.

4. DRAIN supply voltage = 13 V, starting junction temperature (TJS) = 25°C, L = 150 mH, IAS = 1 A (see Figure 11).
