7.3.4 Output Stage

Figure 7-8 shows the TMAG5213 open-drain NMOS output structure, rated to sink up to 30mA of current. For proper operation, use Equation 1 to calculate the value of pullup resistor R1.

Equation 1. V r e f   m a x 30 m A ≤ R 1 ≤ V r e f   m i n 100 μ A

The size of R1 is a tradeoff between the OUT rise time and the current when OUT is pulled low. A lower current is generally better, however faster transitions and bandwidth require a smaller resistor for faster switching.

In addition, make sure that the value of R1 > 500Ω so that the output driver can pull the OUT pin close to GND. Generally, TI recommends to use a resistor with a 10kΩ nominal value.

Note:

Vref is not restricted to VCC. The allowable voltage range of this pin is specified in the Absolute Maximum Ratings.

Select a value for C2 based on the system bandwidth specifications as shown in Equation 2.

Equation 2. 2 × f B W   H z < 1 2 π × R 1 × C 2

Most applications do not require this C2 filtering capacitor.
