9. Electrical Characteristics (Continued)

All parameters given are valid for 7V ≤ VBAT ≤ 18V and for –40°C ≤ϑambient ≤ 125°C unless stated otherwise.

No. Parameters Test Conditions Pin Symbol Min Typ Max Unit Type*

* Type: A = 100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter

Notes: 1. EN, DIR, PWM = high

2. The use of X7R material is recommended

3. For higher values, stability at zero load is not guaranteed

4. Tested during qualification only

5. Value depends on T

OSC

; function tested with digital test pattern

6. Tested during characterization only

7. Supplied by charge pump

8. See section “Cross Conduction Time”

9. Voltage between source-drain of external switching transistors in active case

10. The short-circuit message will never be generated for switch-on time < t
