FUNCTIONAL DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
Figure 7. Functional Internal Block Diagram
SUPPLY VOLTAGE: FILTER/DIVIDER, BANDGAP,
AND POR
An input filter and divider provides a clean image of the
battery to the digital regulation loop circuit. The divider ratio
can be adjusted by OTP.
The supply block provides the voltages for the internal
blocks of the 80310:
Main logic
Analog permanently powered or not
LIN transceiver
Charge pump
The purpose of the POR block is to generate a clean
power-on signal to the main logic.
The Bandgap block provides the voltage and current
references for the other blocks.
POWER STAGE: CHARGE PUMP, DRIVE AND
PROTECTION, CURRENT MEASUREMENT
The power stage of the circuit consists of the gate driver
with a charge pump and protection to control a low side driver
switching the excitation current. A short-circuit is
instantaneously detected and the excitation current is turned
off until the next regulation cycle. A freewheeling diode is
inserted between the EXC and GND pins, across the
excitation coil for the energy recirculation.
The current measurement block provides a proportional
value of the excitation current flowing in the high side switch.
LOGIC AND CONTROL:
DIGITAL
The digital block gathers all the digital functions of the
device. The main functionality is described in the device
operation paragraph.
CLOCK
This block is the clock reference for the digital block. The
oscillator generates a 5.0 V square wave at the frequency of
4.0 MHz in Normal mode operation.
OTP
This block allows an easy configuration and adjustment of
the circuit. A set of NVM bits can be programmed during the
factory test phase. They are described in Table 6.
PHASE LOW & HIGH
The phase detector monitors the Phase inputs and sends
filtered low and high levels to the main logic when either one
has reached the detection level (1.0 V at startup and 8.0 V
afterwards).
ADC
The analog to digital converter is used in the voltage
regulation loop, in the current feedback and in temperature
measurement.
