Constant-Current Bridge: H-SW G
Oscillator circuitry
*: The on-chip oscillation is controlled by the charging and discharging of an external capacitor (COSC).
The charging and discharging rate (VOSC) of the external capacitor is calculated as follows:

Let the time at VOSC = 0.5 V be t1 and the time at VOSC = 1.2 V be t2, then the VOSC slope (VOSC) is
calculated as:
VOSC = I (t1 t2)/COSC
which can be rewritten as:

Hence, the cycle period of the triangular wave oscillation (fOSC) can be expressed as a function of
